HVAC actuactor replaced, didn't fix problem

[meem]

Pontiac had a TSB on this problem with recommendation to replace HVAC door actuator that lets outside air into the car. I did this but the noise persists. Mechanic thinks the problem is in the switch that determines recirculated air or fresh air. Has anyone else verified this?

Same problem with my 04 Vibe, I don't have a way to fix it. Its out of warranty 43K miles , I hope to find a way to fix it.Do you need to remove the HVAC housing to change that HVAC door actuator ?Whenever the climate control is set to receive outside air, there is a steady tapping noise coming from the passenger airbag area. There is no tapping noise when inside air is recirculated. Outside air will be pretty important this winter, would like to get this fixed now. Has anyone else experienced this problem?

Sounds like the same problem I had. It was fixed under warranty. This is how my invoice reads:"Cause-D1810 Actuator and/or motor1 #88970277Replaced air inlet door actuator asm, internal failure gears stripped."I don't know if "actuator" and "actuator asm" refer to the same part or a larger assembly, but it fixed my problem.Good luck with it.

I've tried two actuators and the problem is the actuator continues to actuate (closes outside air flow) even when the switch is set for outside air. My mechanic said this will burn out the actuator again so we left it disconnected. The problem seems to be in the switch rather than the actuator but I have not seen any reference to this on the forum.

Did you ever get the tapping sound fixed? My '04 developed the same problem about 2 months ago. I ordered the part and am trying to figure out how to replace the unit. However, it appears to a very involved process to gain access to the mounting screws - possibly requiring the removal to the passenger air bag?Do you or anybody have any idea on how to replace the part?Thanks.
