Strange knocking sound
Hi guys
I am getting a weired knocking noise coming from the glove compartment. If the A/C is turned on when I start the car there is a rhythmic knocking sound for 10-15 seconds and then it stops. If the the AC or heater is turned off when I start the car, there is no knocking but as soon as I turn it on, the knocking ensues for 10-15 seconds. The only other time the knocking occurs is after the car has been turned off; after 2-5 minutes, the knocking starts and lasts for 10-15 seconds. Does anyone have any idea what might be causing this knocking and/or what needs to be done to fix it? Thanks!

the hvac unit has 3 or 4 actuators that move the mode, temp and recirculate doors. when the linkage is broken the doors move out of a calibrated range...the clicking is the hvac module calibrating the door range....as it moves from completely closed to open. inspect the hvac actuators behind the glove box
