SOURCE: blower not working on ac or heater etc.

A very common solution here is replacement of the blower motor resistor. The resistor when they break do one of two things.

A. work only on high

B. dont work.

This item is located on passanger side under dash and is usually held in with two small bolts on either side with an electrical connector seperating the mounting screws. It is mounted right in the air box. I replace at least one of these a week in my shop very common item.

This is definitely 100% the Blower Motor Resistor.
Replace this and all speeds will work fine.
This Resistor is defined with 3 to 4 wires going into it, and is located adjacent to the Blower Motor.

I will post an additional comment on Part Number, Price and where available.

Make sure your fan is working properly. When you turn on the heater you are forcing the fan to cool the radiator. It may not be turning on automatically when it is supposed to. Let us know if this helps..

Sounds like a problem with the fan switch. If you can find the fuse for the blower motor, you could pull the fuse to stop the fan until you can get the problem fixed.

AC rund at full blast even while turned off.


You need a blower motor resistor. This will take care of the problem. It is located behind the glove box. Pull it down, and you will see a plug going into the heater box. Two screws, and that is it.

Passenger side fan stays on


If the heater blower motor resistor failed then the heater will stay on full blast to keep your window clear, for safety. If the key is turned off and the fan still blows then I suspect you have an ignition switch problem. Main power comes from the key switch to feed the heater system. The plug at the ignition switch could be melted and making contact or an internal switch problem. The switch is located on the steering column under the plastic cover.Unplubbing the switch should help diagnos the problem.
