why does my car make squealing noises only with the heater on?
Whenever I turn my heater on I hear a squeal, and it does it only while the heat is on. I had a couple incidents where as soon as I would turn on my car it would make a very loud squeal for about 15 seconds, which happened 3 times in the past 2 months. I am really concerned about my heating system, i looked at the belt and it seemed to be in good condition.
Also, my brakes make a grinding noise only when I use them the first time I start my car. I just got new brakes and rotors in August, so they should be fine. But I am still worried with the sound I hear once in a while. Its hard for me because I dont have any car garages I can trust to look at my car and give me an honest answer and not mess everything up on purpose. Is there any ideas of what these problems could be?
