My A/C / heat makes a clicking sound. I think I've localized the sound coming from the right (passanger) hand side vent. Has anyone encounted a problem like this before?

 

yeah, but mine comes from one of the center vents and can only really be heard when on 3 to 4 fan speed. After that, the air flow covers the sound. I have no idea what it is and now I just avoid those speeds which also helps me avoid the Chrysler dealer.

 

Clean out the blower motor. The noise will go away.

 

how do you do that? Do I get one of those computer co2 air blasters and blow in the vint? or is the blower motor something completly different?

 

it could be a recurcit valve on the passenger side does it sound like a mouse or a click. I have had clicking and it being a bad CD player before as well.

 

Look at the service manual. It's in the panel under the glove compartment. Drop two screws and remove the cover. Remove the cover for the blower motor cover, then unscrew three screws. Blower motor drops out. I removed two dead and hardened crickets from it and the sound went away.

 

I am again very happy with the information available on this site. This morning I started up my car and turned on the a/c and there was a weird clicking sound, went right to this forum, and found this and was able to quickly fix it. In my case it was only a leaf. Im glad that I dont have to take it into service that probably would have taken all day, and cost an arm and a leg. Thanks!!!
