The heater / ac blower only works on high. It is not the blower or the control switch or the blower motor relay. Please help. Thank George

    My problem is similar, however in addition to only running on high speed it remains running even after the key is off.



    Have not replaced anything yet, because not sure what is problem. I have been told everything from a/c control head, relay, blower resistor?



    Thanks in advance.

    I have the exact same problem. The blower will only work on the 2 highest settings.

    Fan went out. 30 amp fuse in engine compartment had blown. Replaced fuse and I was left with high speed only. Replaced the resistor (it was definitely fried). Still only have high speed. Did I miss something?

It is the blower resister. I purchasted one at auto zone for $18.00. It is located under the passenger side dash. You need to remove the glove box and the plastic cover under the dash to expose the blower motor. the blower motor resister is right next to the motor. Simply unplug the resister remove the two screws and replace. I did this and now my fan works on all speeds.

Heater/ac blower not working, at times it only worked on high, or not at all. i've replace the resistor, could it be a relay or ?
It is not a relay. If you have replaced the resistor pack, then the blower motor speed control switch on the dash is bad. I am assuming you know the blower motor is good.

I only get the fan to work on high speed, the lower speeds do not work
Hi!!
The Blower Motor Resistor also called Manual Temp. Control resistor), is fried, replace. The price with floor console $25 and without floor console $65. here is a pic.

the resistor is located on the blower motor housing, fastened by two screws. It is the part where the electrical plug connects, the plug on the pic. goes to the blower motor.
A HELPFUL - 4 THUMBS rating for this solution would be greatly appreciated. Thank you for using FixYa.
