Question type: Maintenance & Repair

tThe sound is a high pitch chirping noise, sounds like it could be a fan maybe? Is there a motor for the rear defrost? The noise comes and goes but only when the key is on or when the car is running.

That is internal temp sensor. There is a fan in there and I've heard (haven't had to do this yet myself) that you can remove and clean it to lessen or eliminate the sound. Be careful as things are easier to break in our 'older' cars. Hope this was helpful.
