for Quality replacement parts and the
best service on the internet in this
video we're going to be replacing the um
temperature door actuator on this O2 GMC
Sierra this is uh usually the problem
when you turn your uh temperature
control knob and you don't get any
warmer or cold air um you're either just
getting warm or just cold or just one
temperature uh tools you'll need are a 7
mm socket and a 732 in socket ET with an
extension and a
ratchet on the passenger side there are
four 7 mm bolts to remove one
there one in
there there's one up in that hole right
there can't really video it and then
over here closer to the gas
pedal uh there is
one right there and once you remove
those bolts just reach in kind of pull
it down and other
way okay the
actuator is right down under
here it's held in with two bolts There's
7
32s one of them is right over here
the other one's on the opposite
side a little more difficult to get
to kind of have to stuff the wrench in
there but it starts coming out and you
can disconnect your wrench and just use
the socket
okay so the actuator
then comes down and out and there's a
little connector right here just push
and disconnect
very important when replacing one of
these actuators make sure that you do
not power the actuator up before it's
installed um so make sure your key is
off and you'll see that I actually
install it before I plug it
in okay
so
reinstall push it up
in get it on the pin in there
here okay now I'm starting this bolt
over
here just use my socket
okay and the final part is to put your
uh cover back in place um you want to
push it up in there um you push it kind
of against the firewall first and I'm
sorry about shaking around a little bit
here um just trying to film with one
hand and push it up in there with the
other uh push the front of it up and in
first and then make sure you have
everything lined up okay and as you can
see here um there's are the passenger
side Outlet holes make sure those are
all lined up and then start your um end
bolt here and then I'd recommend
starting the one over near the driver's
side um once you have those lined up and
the other two middle ones go in pretty
pretty
easily we hope this helps you out
