2001 Oldsmobile Silouette Rear Air Problem

I have a 2001 Oldsmobile Silhouette and have recently discovered
that the rear HVAC blows hot air when the AC is activated. The front has
cold air coming from the vents, but the back has hot air blowing. The
temperature of the air is always hot, even though I have tried adjusting the
temperature setting using both the front and rear controls. I pulled down the overhead control and there is no valve or anything that is stuck...basically just a plug and play harness. Did a search but seems this is something more in line with a Dealer repair vs a regular novice mechanic such as myself. Would you agree? Or is there some other place I can look that possibly has a sticking actuator or valve?

You may have an issue with the mixing door found under the dashboard. It may be stuck or the actuator that moves it may be faulty. Check also the linkages if they are OK.

AC/heat doesn't come out front vents. Can hear


try a vaccum leak under the hood. Look and listen for any little sounds of air blowing out. Also the door switch may not be turning to vent it may be stuck on one side, like defrost!

1998 Oldsmobile Silhouette a/c blows cold in rear but the front vents blow hot air. A new condensor was just installed and a/c charged.


Hello.Maybe I can steer you in the right direction. There is an actuator temp,door motor.It may be hard to find,but most of them are on the bottom of the blower box about where the ac hoses and the heater core is,under dash.This motor has gone out,it switches from cold to hot ,and all in between .Hope this is helpful.If not let me know.roniecon@gmail.com
