I just bought a 2002 Ranger XLT, it's a nice truck but needs a few things fixed. This post is about the fan switch, the first 3 positions blow almost no air at all, but the high setting works fine. From what I've read it's probably the blower motor resistor, question is, where is it? I thought it would be in the engine compartment near the blower motor, but I don't see it, please advise........
