It sounds like your blower motor resistor, located next to the blower motor itself. It is located on the right side of your dash down by your feet if you are sitting in the seat. GM part#15218254 around $20. Hope this helps?

There is a seperate blower motor relay for the high setting. check that first. It could be in the fuse box under the hood but i think it is near the blower motor... behind the glove box.

Heater / air conditioner fan control doesn't engage fan. Previously, it only worked in high speed.


I would replace the blower motor resistor first then see if that corrects this. The resistor is located next to the blower motor under the dash.

Heater and air conditioner blower switch.


Check the resistor first. It may be bad. Should be under pass. side of the dash close to blower motor mounted in bottom of evap case. Remove it and try known good one first before going at the switch. If it works on high then the switch may be okay. Good luck.

I have a 2002 Elantra. Yestreday the lower fan speeds on the air conditioner fan stopped working (positions 1,2,3). The High speed (position 4) works. Any ideas how to correct?


The blower motor resistors or fan switch itself are defective.
High speed has no resistors B+ goes straight to blower motor.

My air conditioner only work on high. It is clicking in on the low setting but will only work in high. We checked the two fuse panels and they are all good, what else could be the problem.


I own a 2006 HHR, had the same problem, I found water leaking onto the blower motor which caused the blower motor to fail.
I replaced the blower motor & blower motor resister. No problems. (I also fixed the water leak)
The blower motor isn't fun to replace, you have to use a box cutter knife to cut out the blower motor.
When you buy the new blower motor it will come with proper instuctions on how to cut the old one out and install the new motor.

Air conditioner fan runs on high only


Check the blower motor resistor pack.
This is usually located in the blower motor ducting in the air stream.

Fan motor switch on 98 jeep cherokee only works on high


In many cases this is the result of the blower motor resistor having gone bad. They are often located in the housing that holds the blower motor but I cannot say 100% for sure with the Jeep Cherokee.
