of the dash? I have a 2004 gmc envoy and I have a loud grinding (errrrrrrrrrrrrrrrrr sound) coming from behind the center of the dash. It will start when on ACC and restart on startup then stop, then start. This happens 3 times with the second time being louder and higher pitched. This happens for approx. a minute then stops. But will happen everytime i turn off the car and turn it back on. Both heater and A/C work fine and same with defrost, the noise doesnt change when heater or A/C are on, sounds like it goes through a cycle. It sounds like the recirc actuator but a lot faster with 3 stages and the second being higher pitched
Its gotten really annoying,
Thank you
