My 2002 Olds Alero the fan is loud and blows no heat

another good place to take you car is Car Pretty On Machenry ave

The are in the yellowpages

When the fan motor is loud it means its out of balance. Kind of like a dishwasher.

Could a business card or two have slipped through the defrost vents ? or maybe leaves have accumulated in the fans squirrel cage.

A heater motor isn't hard to remove. Usually above your feet on the passenger side held in with 3 or 4 screws and one heavy wire.

more than likely it is just low on power steering fluid. system might have air in it now. so after fill power steering unit to proper level driver the car and check fluid level again. and add more if needed . I believe car should have motor running for when checking fluid, same as transmission.

Check motor mounts.

make sure the cooling fan is working also flush out the fins on the condenser and raidator

crank sensor-known issue with gm's

Make sure that u get all the air out by turning the steering wheel from left to right.. And most important make sure the power steering fluid is for GM product.
Hope this helps..

Had same problem. Replace Blower Motor. Over a 100 dollars at local parts store, but found online for half price. About 30 minutes to replace. http://www.rockauto.com/catalog/raframecatalog.php?carcode=1431961&parttype=6916
6 screws to remove glove box, One plastic nut on kick panel and 3 screws hold the blower to the air box.

I have a 2002 nissan Maxima. The AC controls only blow on level 4. No air or heat blows from level 1-3. What do I need to do to repair this problem?
