You might have to change your fan belts or adjust them tighter. You should have two belts one for the air conditioner and the other for the fan for the radiator, change them I hope this helps.

After turning off the car a whining noise is coming from the front


Hi!!

It sounds like the radiator fan bearings, that's the only thing that keeps turning when the engine is turned of. The noise is allways there but with the engine noise you are not able to hear it.

The radiator fan motor is sealed so it's not repairable. They cost $75 to $100 depending on your vehicle and it is fairly easy to replace. Take the vehicle to a radiator shop or any auto shop for second opininon..

Don't forget to rate this post!! Good Luck!

Almost no air comes from the ac vents but fan is on high. This happens on auto and also on econ.


The 1992 was prior to Buick putting cabin air filters in so there is not a possibility it is clogged. So more than likely your blower motor is going bad or your fan control switch is bad. Does this problem occur with heating as well as AC? Does it change if you switch between blowing on floor, face, window(defrost) If it doesnt change based on location of blow and type of air temp then I would start by turning fan on high and placing head (ear ) against dash in center of console area. Have someone turn fan knob from low to high with engine OFF...After goign from low to high and back a few times you can see if the blower motor is responding to signal from switch. Listen for a whine, squeal, rattle, or humm. A whine or Humm would indicate a bad blower motor... Squeal or rattle a bad squirrel cage/fan blower blades. If you hear no noise and no perceivable change in blower speed/noise then its possible your switch is bad. Unfortunately the only way to definitely diagnose either is to pull the switch from dash and use multimeter to test for voltage change and for blower motor to pull dash. There is a digital control unit for your car as well. Although rare sometimes the wires on this can loosen or it can go bad. But since you didnt state teh fan wasnt working at all and you are getting cool air, that woudl be teh last thing to check

A/c suddenly stops blowing


Maybe your blower fan is faulty.
The whine you heard could be dry/seized fan motor bearings or foreign matter (such as leaves/twigs) in the fan.
If fan motor is faulty it will need to be removed for repair; but first check as below:-

1) Check fuse is ok.
2) Check motor runs if power applied directly to it. - If motor OK, check:-
3) speed resistor module (usually in fan ducting, in air flow),
4) fan switch operation.

Whining noise when AC or heat is on coming from engine compartmen


I suspect it is the blower fan and the ductwork for the air intake to the blower picks up the air in front of the engine compartment.

It would also be a good idea to have your alternator checked and use the A/C heat controls to see how much the blower motor is demanding from the alternator. Autozone and Oreillys will check the alternator on the car for free.
