Thread: 04 Grand Prix heater blower motor

fan runs all time even when ignition is off. Pulled every relay & fuse under hood and dash, nothing controls it.( No "blower fan" is labeled)


TIA.


SR/WA

J fuse #30 controls the blower motor...marked as: battery 4 in the power control center under the hood.......go figure.

Turns out the fan blower power module, located to the right of the blower motor has failed, in order to remove the stupid thing one has to use a hammer & chisel to remove the plastic brads on the bottom of the module.

i had the same problem got out and the fan was still running its the blower resistor.

Thanx GP;


The parts people call it a HVAC blower control switch....$74.00 + tx.

Am wrong on location of switch....is on the left side of blower motor.

i think its on tht side it got black and purple wires going to it. its like a five prong plug
