Have a 2003 Silverado and when a/c is on, the two vents on pass. Side blow hot. Middle and left blow cool. Tried the recal. Deal, but it was not very a very clear procedure. Need a good procedure before I go further. Which actuator controls what? Thanks.
The recal is a bit flakey, I have the same problem; but on the driver's side.
Like you, I'll have to fix it soon.
Your problem is probably the passenger temp actuator.
I expect your HVAC is like mine; if so, there are two temp actuators on the bottom of the unit.
You need to remove the trim panel below the glove box.
You should be able to see the two actuators, the one near the centre of the dash is driver, the one under the glove box is passenger.
There are some YouTubes on changing them.
Even some on repairing them.
After you remove the actuator (3 screws, I think you need a 4mm socket) try turning the temp door shaft by hand
If it turns easy, the actuator is bad
If it's hard to turn, the door is jammed.
If jammed, try removing the blower fan so you can get your hand in there to clear the obstruction.
I need to go through my books and refresh my memory, I will also look at what Ray said. I have a 93 Silverado and my sister has the 95 Yukon, so I know they are similar. I need to look at something about getting the motor or blend door in the wrong position if I remember right.
Hi guys, if you have 2 zone heat/ac, the drivers side is just about the middle of the dash, on the bottom of the box, the passenger side is below the glove box also no the bottom.
You need to remove the trim panel to access. I think they are 3 screw, but not sure. Pretty sure you need a 4mm socket.
I'm not sure about the single zone, it may be behind the the glove box
I just pulled the servo above the throttle and the one behind the glove box and they are similar and have 2 screws holding them in. I also was at the local Pick N Pull here and noticed that 90 to 99 all the servos look to be the same. Maybe the later trucks are a little different. I also noticed that when looking up new servos for these 90s trucks, the prices are all over the place, from $30.00 to $70.00 and higher.
I will also apologize for highjacking this thread, sorry about that.
