HOW TO TROUBLE SHOOT THE BLOWER FAN.

THANKS FOR THE INFO...I WOULD ASSUME THIS PROVIDES POWER DIRECTLY TO THE FAN MOTOR, BYPASSING THE RESISTOR THAT CONTROLS THE FAN SPEED.

Yes

ANY SUGGESTIONS ON THE EASIEST WAY TO DO THAT..I DO HAVE 12V BATTS TO HOOK UP TO IT. OR WHAT WIRES I NEED TO ENERGIZE. THIER IS A SINGLE PURPLE WIRE ON THE UNDER SIDE OF THE ACTUAL HOUSING ALSO..I UNDERSTAND IF YOU DONT HAVE TIME TO EXPLAIN..YOUR INFO HAS BEEN HELPFUL ALREADY...THANKS

Make sure the blower motor has a good ground. Do u have any meters , volt ohm or multi meter to check the power and ground.

YES AND IT APPEARS THE GROUND IS RIGHT NEAR THE BLOWER HOUSING. I HAVE A MULTI METER

Check continuity for a good ground and check for voltage at the purple wire or and 12v to the blower pin.

THANKS SO MUCH
