So when my AC or heater fan is on it works fine for a while. When hit a big bump or sometimes if I turn to sharp I get a horrible squeal. if I turn the fan off it's fine and I can turn it back on...until I hit another bump. Really sucks when I need to defrost. Does anyone know whats going on? Is this a Grand Prix problem or just my problem lol.
