The bearings are going in your blower motor. You should be able to access it from under the dash, or under the hood. In the good old days they were all accessible from under the hood, but that made it too easy for us. I'm pretty sure if you remove the lower right insulator panel, below the glove box, you will be able to see your motor, and it is held in by three screws.

My 01 cougar makes a noise like a pump is going out or is clogged could someone told me it sounds like the ac, but it does it even when the ac is off your thoughts


there are several items running that can produce a noise
the water pump bearing will be a grumble or a tinny rattle , the idler pulleys will be a rattle, the ac pulley is on a bearing separate to the ac operation and is running all the time and the problem noise could be from that bearing
the alternator bearing will make a medium pitch rumble and if you have a viscous ( clutch hub) fan hub the bearings in it will produce a noise
an accredited mechanical shop will have a stethoscope and a good mechanic will be able to determine exactly where the noise is coming from

I have a 2006 Mazda3. I noticed whenever my air conditioner or heat is on it makes a sound like a lawn mower when I acceralate. Any ideas of what this could be ?


Well, I think you can rule out the AC/heater fan inside the car. That would make noise even just sitting in the driveway.

Many/most vehicles are designed to run the AC compressor not only when the AC is on but also when the defroster is on. This is to keep the AC compressor lubricated through the winter months also.

It should not be a belt problem as that belt is always turning anyway which should then rule out the pulley bearing at the AC compressor.

I do suspect your problem is a major internal failure of the AC compressor. This can be easily checked by a technician [or yourself if qualified]. Locate the electrical connector at or to the AC compressor. Two people: With the AC turned on, in park, increase the engine speed so you can here the noise. Disconnect the AC compressor electrical connector. If the noise stops instantly, the compressor has failed. A quite expensive repair. Have a reputable shop locate a re-manufactured compressor for you. That will help some on the cost.
Bestaluckto you!!

HVAC is making rattling noise


Your fan that is attached to your blowermotor is loose, causing the rattle, or the bearings in your blower motor are bad, causing the shaft and fan both to rattle.

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

Only 4 & 5 speeds work on the AC fan dial...1-3 do not blow any air but you hear the AC kick in


There is a blower control module in the heater case that is known for going bad.Also it will sometimes burn where the connector plugs in.

Ac not working makes a fan rattling noise when ac is engauged


SOUNDS LIKE YOU ARE LOW ON FREEON YOUR SYSTEM NEEDS A CERTAIN AMOUNT OF PRESSURE TO TURN ON AND OFF SO THE FAN TURNS ON WHICH IS NORMAL BUT THE CLUTCH ON THE A/C COMPRESSOR IS NOT TURNING ON 1/2 -1 POUND NEEDS TO BE ADDED TO YOUR SYSTEM
