Re: clicking noise
Every once in awhile my cd player will make a clicking noise but its mostly at first start up, and does not happen all the time. a lot of these factory radios do this from time to time. I have had mine replaced several times. Also it could be a mode door accuator which is a motor mounted on the HVAC system to change the modes of operation, as in defrost mode, floor mode, and vent mode, also for the temp blend door. If it is leaves in the fan, you should hear more noise towards the glove box area behind it.
