If you are talking about the blower motor under the dash, a critter could have stored nuts or acorns in the HVAC system.
You may need to take the blower motor out and take a look.

    Dropped the blower motor and there was a chipmunk nest. Fortunately appears the critter hadn't moved in yet.The blower fan now runs fine. Thanks Stephen.

SOURCE: Air condition problem

When you say "noisy", is it a metallic grinding noise? Or, did someone overcharge the system. If the compressor IS internally noisy, replacing it is only half of the job. Anytime that comperssors fail, metallic particles get in the system, from the grinding of the compressor vanes or bearings...and need to be removed. Most of the time, they are trapped in a device called the "receiver-dryer", located next to the condenser in the front of the car. So, replace the compressor, replace the receiver-dryer, and evacuate the system. Hold a vacuum for 30 minutes, and then recharge. Not replacing the receiver dryer will damage the new compressor.

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.

AC/Heating unit has died in the winter.


This clicking sound may be more evident now that you are aware of a problem ? You may have a bad plenum actuator switch . It is mounted on the side of duct work and they will make a loud click sound

Air Conditioning only works during winter and heat only works during summer!


Miss Kristin, your situation sounds more like the air flow blend doors/flaps under dash are operating, but incorrectly. All these vehicles temperature changes are actuated by vacuum from the running engine. In your case it's possible a vacuum line has become disconnected from the blend switch behind the lever or the 2 heat and a/c hoses have become switched. Either way, I believe it must be in the vacuum lines under dash, or possibly no vacuum at all to the blend switch because the main hose from the engine has become disconnected or is broken. Best of luck on this luv.

Gmail.comi have a 97 jeep grand cherokee 5.2 and it overheat when i turn on the air . can the wrone fanbelt make a drifence


Generally no, the fan belt will not make a difference IF it is tight and turns the fan and water pump. A lot of things can affect the temperature of the coolant including the condition of the coolant. I have to switch my 1995 Jeep GC thermostat from a higher degree for the winter to a lower degree thermostat for the summer. I also found that using a syntinic (sp) oil helps during the summer.

The air conditioner went out on my car when i turn it on it dosent do anything i can just hear a click noise like its trying to turn on and when i press the off button it makes some kind of hissing noise...


You might have caught the leak down in time...try adding some R134 refrigerant...if your system is low on the refrigerant...this initially causes the symptom you are describing...I know it sounds silly to add refrigerant during the winter...but you are trying to save the compressor...:) Hope this helps.

The Air Conditioning makes a loud noise when you turn up the fan speed.


Something could have gotten stuck in there, and throwing the fan out of balance, or the bearing on the fan motor are bad, if that's the case the fan blower motor will have to be replace.

Air conditioner fan is making a loud noise


1. Could be a caught foreign object between A/C (air conditioning) fan and cooling radiator, producing this loud noise.
2. Could be a damaged fan blade, mowing the cooling radiator.
3. Could be a loud noise comming from the fan's electrical motor.
4. Could be a broken off fin (small wing) of the cooling radiator, striking the A/C fan, producing this loud noise.

Very loud clanging noises started while driving


Try to remove the belt for the ac and see if you still hear the noise, as it sounds like you may have blown the seal or bearing out of the ac compressor , not sure just a guess.

Fan makes loud noise when i start car


Firstly we need to know what model etc. Noisy fan if viscus could be the viscus itself - fan blade hitting something on the shroud / housing. First check & make sure the small bolts haven't shaken lose. Good luck
