fan clicking noise


Recommended Posts

Posted

Have a strange problem with the a/c fan. I've been hearing this clicking noise coming from below the dash on the driver side when the fan is on at any speed with a/c on or off. But this only happens when the vent is set to dash and as soon as I swich to dash/floor, the clicking noise goes away. And when I go back to dash only, the noise comes back after about 30 minutes. I tried to take it to the dealer and of course, the noise goes away when I'm there. Has anyone had this problem??

It could possibly be the HVAC door mode actuator, as described in this thread.
