What could be causing loud grinding noise when i switch on aircon? Aircon now not working but only makes loud sound.


Sounds like the bearing or part of the clutch in the A/C compressor has failed, or possibly component on a/c fouling on something due to recent repairs however would be unlikely and probably just a coincidence..

Check A/C compressor turns by hand, should be firm but not make any noises.

Check for fouling components related to a/c compressor clutch.

Chirping heater in 99 Buick Century


I've never heard of a core making that noise. And the only reason to replace a core is if it is leaking or plugged up. Chirping wouldn't happen in either of those circumstances. It is probably the fan, although something caught inside the fan blades might also be making the noise. You are lucky that the heater fan is much easier and simpler to pull off. You should do that and see if there was something causing the chirping

There is N-number of possibilities for the car to make loud truck noise or any other kind of noise.

Loud noise when a/c and defrost are on


I would check the fan motor for the heater sounds like the bearing is going out. Does it scream and then go quite or rumble if so it is probably the heater fan. It will run and blow air but it will make a lot of weird noises. If you shut the fan off and the noise goes away it is the fan.

1997 S-10 41000 Miles. Heater blows cold air.


The actuator for the door that switches, the blend dorr sounds to be problem, although at times the actual door can be problem.if it is binding this would cause the same sound. This is a a complicated job if it is the door, not so much if it is actuator.
