The blower motor in our '99 Trooper quit working a couple weeks ago. I found a blown fuse, replaced it and the motor once again worked. Fast Forward a week or 2 and it quit again. Searching seems to indicate most likely a bad resistor or a bad ground (if the newer trucks use the same grounding by oil sender?). I'm guessing the resistor is behind the glove box? How do you get to it?
