Jerry Bransford That's good information, my '97 TJ's fan circuit was much different.

RUBI 4 MY MRS I see you have a ’99, right? I believe that is the year they changed the whole setup & the relay supplies 12v to the motor & the whole speed control is through the ground side. That means the ground path is through the resistor, speed switch & mode switch then to ground.

The mode switch has to be in any position except off to complete the ground through the dark green wire.

If all speeds are out it is probably the speed switch. Try jumping each of the resistor legs to ground & see if each speed works that way.

Jerry Bransford The blower motor's specific ground point is not important, only that it has a good solid electrical connection to the body. I would just find a close by grounding point on the tub and connect its ground there. Or drill a hole near the motor, grind the paint away from around the bolt hole and bolt the ground lead to the tub. I'd use a 12 gauge wire to ground the motor, use black if you can.

If u find out please let me know....
