I have a 2004 mazda 3i with 77k miles on it, whenever I turn on my heat and make a left hand turn or my car dips to right I get a loud rubbing noise everytime the heat cycles on, sounds like a plastic rubbing on plastic kind of noise, and if I put it in neutral and rev the engine the sound goes faster, im thinking possible rubbing from the fan belt on the plastic cover underneath the car it is very irritating and no one seems to know the problem. Again it only happens when I turn left sharp or my car is sitting leaning to the right
Do you

I recently had that problem. Perhaps you already fixed iit. But if not check the bottom plastic cover that protects engine. As it may be bent or out of place because of missing bolts or because of hitting something underneed. As it touching the the bottom pice of the engine that spins when the heater is on.
