So I've been experiencing a common problem with the blood boiling clicking sound inside my glove box when I turn on my AC. So I googled it. Ordered a blend door actuator and replaced it. Tons of swearing getting those screws out btw. I have soup can sized fingers.

Boom, new actuator.
Start up the ac and that clicking was still there.

So if I replaced the blend door actuator which seems to be the problem with most people as that's the only actuator replacement video I can find on YouTube. What other actuator can make that same noise that accompanies a bad blend door actuator.


Sorry if this is confusing and poorly organized post. (It is my first)

Thank you in advance Monte owners.

 

Assuming your '07 is like my '04 (and it probably is), it has what GM calls an HVAC Module (big housing that contains the evap core, heater core, blend doors and so on). It has about 4 actuators:
- Recirculation
- Driver Side blend door
- Passenger blend door

And I feel like there really is a forth, but I don't recall at the moment.

 

Hey thanks for replying. Well I might be wrong about this but would I have passenger and driver side blend doors if I don't have the dual climate option? And if the recirculating actuator make the same clicking sound that the blend door actuators make when they fail?

 

There are 2 actuators on the passenger side, and 1 on the driver's side. Did you replace the one behind the radio, or the one near the passenger's side door?
