rev up your engines today I'm gonna show you how you can get your power windows to
work smoothly for years and years and not have any problems with them now
power windows are pretty simple devices you push a button it sends power and
ground to a motor and it turns in one direction and pulls your window down and
then when you push the button the other way it goes up it sends power and ground
to the motor but in the opposite direction DC motors can work either way
so if you put positive here and negative here they'll spin one way and if you do
it the other way it'll spin the opposite way so you got the same motor and it
just turns one way to go up any other way to go it out now I'm old school myself go you turn it one way it comes down and
the other way it goes up pretty simple nothing really ever goes wrong but
almost all cars have electric windows these days know if they all go up and
down here's a trick we're trying to left-rear one we're trying to make it go
down but as you can see that windows not budging it's just staying where it is
but here's the trick to get them down if they're stuck often they gonna come down
if it's stuck up is you just open the door push the button that lets you go
down and slam it when they're stuck that'll often let them go down again
sometimes they can stick and here's how you can prevent the sticking you get
some silicon spray now don't be confused this says wd-40 water resistant silicone
spray it's not wd-40 spray wd-40 just makes it it's an actual silicone spray
you can use any brand and window it rolls up on these runners you just
sprayed in there you get a little over spray just wipe it off and do the same
on the back where the runner is and you're on it back up and wipe off any
little residue on the outside and on the inside that's a good thing to do on a
cloudy day like today or do it in the shade in the garage you don't want to
spray silicone on hot metal if it gets on you paint you can just wipe it
off especially when it's cold and not sunny outside
it's gonna hurt anything you just wipe it right off and of course do all four
windows up there electric windows this little tiny bit of lubrication and
since as it says it's water-resistant it'll stay on there for quite some time
and here's another trick if you have automatic lowering windows just push it
and let go when it gets to the bottom it automatically shuts itself off so good
feature to use and if you don't have automatic ones when you push it when it
gets to the bottom let go don't hold it on well it's at the bottom because if
you hold that switch on it's continuously sending power to the motor
and the motors gonna be pulling it down straining itself and that's how the
motors get burned out and of course the same thing goes when you put a bag up
now this is an odd car it is automatic down windows but when I let go it stops
so if you got one of these when you get up to the top when it gets to the top
let go because the same physics is involved here if you're pulling it up
and it goes all the way up and you keep holding on to it then it's pushing as
hard as it can and I even seen some of them if they hold them long enough not
only can it damage the motor but it will Bend the regulator assembly did pulls it
up and down no of course the best systems are my wife's likes just where
the automatic goes down then it automatically stops and then when you
make it go up you let go it automatically goes up and then stops if
you have this kind of system just use the automatic stuff all the time then it
will automatically shut up at the right time and it won't have any problems with
over tensioning the assemblies now here's another power window tip that can
really save you money a lot of times as a car ages especially if you driving
tonight if you hit the switch to make the motor go up or down the window
starts moving and you see that the engine either starts out in a lower or
if you're just at a stop sign the headlights might start to get dimmer
don't necessarily condemn the motor and think you have a bad motor as nutty as
it sounds check under the hood first have the
battery and alternator checked first if your battery is weak or your alternator
isn't charging correctly and this test takes about two minutes then when you
turn the electric motor on to make the window good they're up or down they use
a reasonable amount of power at the batteries law or the alternators will
often make the car idle a little weird or the headlights dim at night
and it's really not the motor it's the battery or alternator not charging right
in the past I've had people come over here and they said Oh Scotty when I was
doing my windows it got dull so a guy sold me a window motor assembly for the
driver's side but it still does it then I find out that hey the alternator was
weak wasn't charging and he'd wasted all his money on their window assembly now
if your battery checked out okay and your alternator checks okay and it still
does the dimming or idle and poor when you turn it on then odds are the motor
is just starting to wear out or the regulator and from my experience with
most cars these days if you do have a problem you can easily buy one of these
aftermarket motor regulator assemblies I've seen them where if you bought the
motor and the regulator separately at a dealer it could be almost $400 we didn't
get a motor regulator assembly for under a hundred bucks at most discount auto
parts stores and they work perfectly fine nonetheless trick about power
windows has to do with the switch assembly under no circumstances let kids
spill big gulps on the assembly especially on the ones that have the
assemblies in the middle of the car that sticky syrupy stuff on the switches you
might think oh it's just a switch some of these switch assemblies can cost four
or five hundred dollars on modern cars keep water away from them especially
stinky drinks or whatever you don't want to ruin these expenses they're not
just a simple little switch they're little computer micro circuit board on
most modern cars now you know all about electric car windows how you can keep
them working smoothly as long as possible so you don't have to waste any
of your money fixing them because they break, so if you never want to miss
