    I have a simular problem with my 2000 G prix, however It might work normally while the vehicle is standing still but when you go down the road for a piece and stop and sit the fan motor will be hunting around in RPM. If it is set on any speed setting 1-5 lets say 5 the rpm varies and maybe stops then starts again on its own. I have noticed that in the driveway when set on any fan speed setting the fan is blowing at that speed and you back up and hit the brakes the fan will almost stop but it does not do this when going forward and hit the brakes, so it does not seem to be tied to the brakes, just change in direction.



    Can you help

Heater low heat


check to make sure your cooling fan isn't running constantly, also if your temp gauge says the engine is hot but the heat isn't you have a flow problem. maybe water pump or a clogged/ crimped hose. if your gauge isn't very hot then put some cardboard infront of the grill.

I have a 2002 Pontiac Sunfire. My fan stopped producing air (hot and cold altogether) - from the lowest setting to highest setting does not work.


HI,
sounds like a the heater/ blower fan relay went bad. Unless you're mechanically-inclined you'll need a mechanic to install the replacement.

Do a Google search for the relay or blower motor and/or search for a Chevy Cavalier (same car) forum to find a fix - if you want to tackle it yourself.

Fan only works on high speed


Hi,
Common issue is a blown 'blower resistor'. Call the dealership or an auto parts store for the part, and look on Youtube or Google-it to replace it yourself.

Heater fan will only work on high other settings won't work 2002 Pontiac Sunfire?????


In most cases the heater switch has gone bad. I would check eBay or a junkyard, either local or on-line for a used replacement. The next most probable cause would be the blower resistor. Those are usually around $40. or more (new) at a parts store. Again it is more likely the switch. You can remove the old switch and check for continuity in the non-off positions with an ohm meter. Good luck!

My fan heater only works on the highest setting 6


Hi. This will be the result of a failed resistor switch. the switch controls the current level sent to the blower motor. Once replaced, the motor will operate at your desired rate. This switch is an integrated part of the AC/Heater control cluster, that is mounted in your dash. You will need to remove the trim, and cluster assembly to expose the damaged switch.

Why would my 2002 Jeep Grand Cherokee only blow luke-warm to cold air when the fan is on high? First the heat went on the highest setting, so i used the second highest. Then it started to coll as...


Sounds like you need a blower motor resistor located down under dash on pass side next to blower motor. This is a comon problem and I have changed many of them. thats just the fan speed problem. Ive seen the blend doors break easily on those jeeps. thats inside the heaer core box and moves the flap from hot air to cold air. If it is stuck halfway -or mostly to cold- you may only get luke warm air. If they had the heater core out-maybe they possibly broke it.
