What causes squeaking noise when heat is on in the car?

There are a few different things that can cause squeaking noises in your car when the heat is on. The first thing you should do is make sure that the heat isn’t being directed in a way that’s causing it to come in contact with any metal parts or components.

If your car has a sunroof, for example, and you’re having trouble with squeaking noises when the heat is on, it may be because the air from your vents is hitting the sunroof and then bouncing back into the car.

Another possibility is that there’s some sort of debris lodged inside a vent or ductwork. This can happen if something gets caught up in your car’s windshield wipers or if you accidentally leave something behind after cleaning out your trunk or roof rack.
