The blower motor resistor on a 2002 Wrangler is behind the glove box, on the passenger side

SOURCE: how to replace a blower motor resistor in a 2004 jeep liberty

You have to take the glove box off and it is right behind it, need a #20 Torx to take it replace it. The glove box is the hardest part of the job, I just replaced mine on an 05 Grand Cherokee but it didn't fix it for me, was well worth the $8.60 to try though.

SOURCE: ac blower won't work. Resistor has been replaced 3 times. I think it is the problem now. Is it easy to replace? Where is it?

Blower motor resistors are found on the pasenger side ducts near the blower motor. It should have three wires going to it.

Motor is also energized by a relay. check that and also check that the motor itself is good by running a hot lead right to it. I'm sure you already checked the fuse and know the switch is good?

Yes, you can take a voltmeter, ground the negative side to the battery negative side or to the frame of the car. Then see if you have voltage at the blower resistor first and then at the motor. Track the voltage down till you find where it stops.
