Hey friends, it's Len here from 1A Auto.
Today in the studio, we have a First-Generation Chevy Traverse.
I wanted to go over some of the top problems that we've come to find.
So let's get started.
Now, for our first problem, we're gonna talk about transmission issues.
For this one specifically, it's gonna be for the six-speed automatic transmissions.
Now the cause for this issue is gonna come down to the internals of your transmission.
You have several clutch plates inside there and if one of them goes bad, the 35R which
is inside your transmission, you're gonna have issues.
Some of the symptoms that you might happen to find if you're having an issue with the
internals of your transmission might be shiftability issues.
You might also happen to find that you have a check engine light that comes on your dash.
You go ahead and pull those codes and it's gonna tell you you got something going on
inside your transmission.
Other than that, you might be potentially driving down the highway, it goes one, two,
three, sometimes shifting into third gear, It's gonna have a little bit of an issue or
even sometimes fifth gear.
You might find that you have an issue with the shiftability of the transmission.
Let's go over some quick fixes for this.
Obviously, you're gonna wanna diagnose it first.
One of the best things you can do is go ahead and check your transmission fluid.
Make sure that it's the color it's supposed to be.
If it looks like it's brown or even burnt in any way, maybe give a little sniff and
it has like this horrible smell to it, typically, that's because you went over on your maintenance
for your transmission.
If that's the case, of course, you're gonna have shiftability issues, but let's say you,
of course, keep up with your maintenance like most of us do because we wanna try to keep
our car around as long as possible.
You check that transmission fluid, It looks fine, but you still have the shiftability
issues.
This is gonna come down to an internal transmission issue and it's gonna be a broken 35R clutch
wave plate.
So you're gonna have to tear apart your transmission.
Now, for our second problem, we're gonna talk about the EVAP system purge valve.
For that one, in particular, it's gonna be located right underneath this cover right
here so I'll just go ahead and remove my oil cap, remove this cover right here, and then
there's our purge valve.
The purge valve is an electronic valve that's supposed to open up and allow the vacuum from
your air intake system to draw fuel vapor from your charcoal canister which is all the
way down by your gas tank and come up through here and then get burnt up inside of your
engine's combustion chamber.
What can potentially happen with these purge valves is there's a little valve inside and
if it gets stuck open, it's gonna allow the vacuum to be constantly drawing fuel vapor
through this line right here and it's gonna be trying to draw it into the engine.
The problem with this, though, is that the valve's actually only supposed to open up
when the car's computer says that it's time to.
Essentially, it's only gonna do that when the car's already warmed up.
Some of the symptoms that you might happen to find if you're having an issue with your
purge valve might be a check engine light on on your dash.
If you were to go ahead and pull that code, you might get a code that comes up P0496.
The description for that is probably gonna say flow during non-purge in system, which
essentially means your valve is stuck open.
And of course, if you're having this issue, at the same time you're probably gonna notice
that you have a runability issue in your car, maybe it stumbles a little bit or even hesitates
a little bit.
Aside from that check engine light, you might also happen to notice, as you're trying to
leave the fuel station after gassing up, you go ahead and try to start up the car and it's
just gonna crank, crank, crank, crank, crank, crank, crank over.
It might actually start up after a lot of cranking or even in some cases, it doesn't
wanna start at all and you have to be towed away.
Now we're gonna go ahead and talk about some fixes for this.
Obviously, you're gonna wanna check that check engine light.
You wanna make sure you know exactly what codes you have so you know where you need
to be.
One of the first things I always like to check if I'm having an issue with EVAP system is
my fuel cap.
Go ahead and take a look at that gasket that's supposed to be around it.
If it looks as though it's cracked or damaged in any way or even if you can see dirt or
debris on the inside of that where it should actually be sealed and away from all that
contaminants, you know that you have an issue with the fuel cap.
I wouldn't just necessarily stop there though because this isn't actually directed towards
that but if your fuel cap's bad, you need to replace it.
After that, I'm gonna come up underneath the hood, we're gonna remove this cover right
along here and we're gonna go ahead and check out our purge valve.
The best way to continue to do this is to go ahead and disconnect the EVAP line right
along here by squeezing these tabs.
We'll draw that off.
And then, of course, disconnect the electrical connector as well.
Now, at this point, having the electrical connector off of here, this should be stuck
in the closed position.
It should not be open.
The next thing I would do is make sure that the oil cap's on and then hop inside the car
and start it up.
We're gonna come right back out here and we're gonna feel along this area and if you feel
any vacuum, like, maybe your gloves getting stuck on there or if you're not wearing gloves,
you can try a little piece of paper over it, if it feels like it's getting stuck onto it
with vacuum, then that means that your purge valve is stuck open and it needs to be replaced.
If you were going to replace it, there's one mounting bolt right along here.
Now, for our third problem, we're gonna talk about front struts.
I have one in my hand right here.
It's not the one for this particular car but it is something that I can show you.
Now, the strut itself is, of course, gonna be responsible for the suspension of your
car.
So every time you hit one of those bumps, this is supposed to compress a little bit
and of course, take away some of the jaunts that you might have potentially felt inside
of that passenger compartment.
Other than that, it's also meant to help ensure the fact that the wheel is staying firmly
to the ground so if you hit that bump, it's not just gonna come shooting up and then hang
out for a little bit and then make its way down.
It's gonna go up, down real quick so your wheel can remain on the ground.
Common things that might potentially happen to your front struts.
You could potentially have an issue with the cap which is this area right up along the
top.
That's gonna be the area that connects the strut to the actual body of the car itself.
If for some reason something happens with the cap and it's loose inside, you're gonna
hear a clunking noise.
If you were to look inside of this springed area here, you might potentially see some
oil looking like it's coming out and then down the front of the strut there.
If that's the case, that means that your strut inside is blown.
You have a little bit of oil coming from it which also means that the gas that's supposed
to be located inside also came out at the same time.
Other than that, if you take a quick look at this one, you might potentially see that
you have a broken coil spring.
This spring right here is, of course, supposed to absorb a lot of the shock if you hit one
of those bumps or anything the like.
So if your spring's broken, you're gonna hear like a [vocalization] noise and maybe even
a creaking noise as you're going over bumps.
Aside from that, any damage to your front strut, more than likely you're gonna hear
the noises over bumps and you might even feel a loose or even squirrely steering while you're
going around curves.
Now, once again these aren't necessarily parts for this particular car but if you were to
look down here, you can see a couple of the parts that you're gonna need to get.
If you had an issue with any of these things, you're gonna typically replace them all at
the same time.
You would have your strut assembly.
You would have a coil spring that's gonna go around that coil assembly and then up along
the top, you need to have a mount of some sort.
Obviously, when you're putting this together, you're gonna have to condense or compress
the spring right here which is gonna be very difficult.
It's not something that you can do with your hands.
You're gonna need a special machine for that and, of course, you wanna make sure you're
safe as possible because it's gonna be under a lot of pressure.
The easiest way to go ahead and fix something like this if you had an issue with one of
your front struts is to just get it as an assembly.
You can get it with the strut, with the spring, and, of course, the cap all at the same time.
So if you do one, you're gonna do them as a pair and of course, make sure you get yourself
a four-wheel alignment.
Now for our fourth problem, we're gonna talk about a master window switch.
The master window switch is gonna be located on your driver's door and the reason why it's
called the master window switch is because it controls all the windows in your car.
Now, knowing what I said about the master switch controlling all the windows in your
car, if you have an issue with one of the windows not working, it doesn't necessarily
mean that it's the master switch that's the issue.
If for some reason I tried to power down that left rear window right here by the master
switch, it didn't wanna go down.
The next thing I would wanna do is continue over to the actual window itself or the door
that the window's in and try that switch.
If the window worked by using that switch but not the master switch right here, then
you know you have an issue with the master switch.
Now, the master switch can technically go bad in several different ways.
It might just stop powering one of the windows or even sometimes multiple windows.
Why might something like this happen?
Well, let's say maybe you left your window down like this.
You went for a little ride.
You wanted a little bit of fresh air.
You got to where you were going and you went inside.
Well, that's great.
Maybe, a little bit of rain came down while you're inside and you didn't really think
too much about having that window open.
Well, rain comes down, gets moisture on the switch and next thing you know, you're gonna
have a buildup of corrosion inside of your window switch.
So now here's a master switch out of a different car.
You can tell this is only for two windows but it could potentially work for four.
If I was to look on the backside, you can tell that there's gonna be a circuit board
and a whole bunch of little circuits that need to make electrical connections.
Looking closer at it, I can see that there's a whole bunch of green crusties on this and
the green is corrosion.
Why is there corrosion?
Well, moisture got on your window switch just like this one.
So now we're gonna talk about fixes for this.
Let's say, maybe, potentially you just came out from when you went inside and you happen
to notice, in the rain, you left the window down.
You open up the door and you can see the switch is just covered in water.
You're gonna wanna make sure you get the majority of that water out of there.
Use something that's absorbent such as a cloth or anything to like.
If for some reason you don't feel as though you can get as much water out of there that
you think is inside there, maybe you left the window down in a heavy rainstorm, the
best thing that you would wanna do is go ahead and remove this area right here, remove the
switch itself and then try to blow it out with something, maybe, such as compressed
air or even put it in, like, a nice bag of rice.
You wanna try to get out as much that moisture as possible so that way there the switch doesn't
go bad internally.
If for some reason you just find that one of the windows doesn't work, like I said,
you try using the left rear window or even the right front or any of them, it doesn't
work and it has corrosion, well, then you're just gonna have to go ahead and replace that
master window switch.
All right.
So let's move along to problem number five.
Let's go ahead and lift this tailgate and we're gonna talk about the strong arms.
You're gonna have multiple strong arms on your tailgate and the reason for that is because,
of course, it's gonna be very heavy.
You need something that's gonna be able to support this while you have your head under
there.
This is, of course, for safety.
These strong arms right here are pressurized.
If for some reason they lose pressure and you can see oil coming out of them like that
front strut that I showed you before, you know that the gas and oil inside there has
been blown out and it's not gonna be efficient.
Some of the things that you might happen to notice for that is, of course, you lift up
your tailgate, you go to put in your groceries, and this thing just keeps falling down on
you and you either have to hold it up like this or even try to put something along here
just to hold it so you can do whatever it is you need to do.
Sometimes you need to have two hands and holding this up at the same time just isn't very efficient.
Now, obviously, we're gonna wanna fix these strong arms.
When you do it, typically you're gonna do them as a pair.
You don't just replace one just because one's leaking.
When you do it, do them one at a time though.
Go ahead and just pop off these little clips right along here and then you can pop this
right off of the knob that it's set into.
You would do the same on the other side right there.
Go ahead and put in your new strong arm and then do the same to the other side of the
tailgate.
Okay friends, so that's pretty much what I've got for you for some of the top problems that
we've come to find on a First-Generation Chevy Traverse.
Of course, every car has its problems, Maybe you've got one of these cars with problems
of its own.
