I am getting noises (mechanical clicking) out of the front and rear of my Tahoe (it has rear a/c and heat). It has sounded a/c related, and the dealer in fact said it probably was an actuator, but could not replicate the noise. I have found info on the actuator under the dash, but can anyone give me any info on the rear actuator? Location? Access? Cost? Available aftermarket?
Thanks!

 

If it's one of those small headliner intake vents, you should pop out the small circular vent and see if the fan is in the right position.

If it is and still makes noise, replace it.

You can pick them up online for around 30 bucks.


I had the issue and simply adjusted it and it stopped.
