It sounds like you have automatic climate control. There is a fan module that controls the blower motor which is causing your problem. In most fan motors the module is built into the motor itself. The parts associate will know by your vehicle identification number what you have in it at any GM parts store

AC/Heater blower stays on with key off. Have to remove 40 Amp fuse under hood to turn off.


The most common cause of this is that the blower motor speed dropping resistor is defective, I suggest you try that first. It is located in the air ducting (the connector harness sticking out) near the blower motor. See picture below.

2001 dodge caravan Ac comes on but will not blow ay any speed . I replaced blower motor resistor.


try tapping the bottom of the blower motor with the blower motor speed selector turned to high and the key on. If the blower motor starts working replace it.

Another thing you can try is unplugging the blower motor and supplying your own power and ground wires to the blower motor. It doesn't matter what pin on the blower motor you supply power or ground. It will work either way. If it doesn't than replace the blower motor. If it does you might have a bad control head.

You could also have a bad blower motor relay or blower motor fuse located in the underhood fuse block. There should be power at the dark blue wire at the blower motor with the key on and the fan speed set to any position.

here's a how to article I did on blower motor operation.

A/c fans wont blow


If the fuse is blown for the blower then there is a short, that is not an answer, go to the blower and check to see that the blower motor connector has 12 volts to it when the blower is set to high speed on control, if it does then u need a new blower motor, if it doesn't then the control switch is defective or the blower motor speed control resistor is defective.

Replaced blower motor, now runs continuously.


Run's continuously ? High speed , low , med 1,2, 3 . ????
Probably the high speed relay contact's stuck closed . The fuse for the high blower is hot at all times , low blower fuse is hot only with key on. It sparks becaused the motor turns on . If it had a short the fuse would blow . The blower motor relay is part of the resistor pack near the blower motor .

Blower won't shut off


You will need a Blower motor resistor and maybe a blower motor resistor connector end. If you look under the dash on the passenger side(may need to remove smooth black cover, vents will be sticking out) you will see a connector going straight up into the blower motor resistor(7 wires/slightly in front of blower motor). Pull out the connector and check for melted terminals/wires. If no melted terminals just replace blower motor resistor with part # 89019088 per GM to revert to part before 04 in order to stop blower motor resistor relay from hanging. Let me know if i can help more.
