Heater/AC Control

The switch only works in the high position. I've replaced the switch and still have the same problem. Another member suggested it might be a resistor. Any ideas? Where is the resistor?

might be behind the glove box on top of the housing

Is it the black relay? That's all I found on top of there.

There is a relay and fuse under the hood in fuse box. I had the same prob and changed mine. Hope this works.

I finally fixed the problem. It was the blower motor resistor pack. It is located behind the glove box on the blower motor. There is a relay on top of the blower motor and the resistor back is under it. Just unplug it and take out a few screws. The part was $16.20 at Auto Tire Parts/NAPA and $25.00 at Oreilly's.

Hvac fan speed problem

I had the same problem some of the other guys did. My fan only worked on high. I replaced the Blower motor resistor and it fixed my problem. I got the part from autozone for $15.99. Thanks guys!!
