2002 Jeep Wrangler blower motor is not working on any speed. Not sure which fuse covers blower, so checked all and can't find one blown. Assume it's not resistor, because it's not working on highest setting. Anybody know for sure which fuse should be swapped out, or recommend next step?
Re: 2002 Jeep Wrangler blower motor is not working on any...
If fuse is good, then turn switch on, and take a voltmeter or test light and test power to the motor. If there is power, then motor is bad. If no power, than switch or relay is bad.

this is a TJ wranger,
the HVAC chapter and 8w wiring chapter covers all that.
as posted here 100s of times. (sure finding it in 1zillion spam hard)
8w-42
blower dead on HIGH, (answering
for...)
Fuse FB8
Fuse PDC #1 to blower relay.
or bad relay
or bad controls.
on high ?
bad fuses
Hi works, and others speeds dont, bad switch or blower resistor bad.
hot wire the blower motor , does it work now. bingo, bad controls.
Hello,
You may want to try your fan on all speeds. If it will work on high, you have a bad resistor for the fan motor. ( high speed doesn't go through the resistor ).
If it doesn't work on any speed, I would check the following;
1. Make sure the fuse isn't blown for the fan blower motor.
2. Check, or have checked the wires between the fan control switch and the fan blower motor.
3. Have the fan control switch checked.
4. Have the fan blower motor checked.
Yes I would go with the switch, BUT, does it have a resistor bank? That is, how does it reduce the speed? Many systems use resistors to lower the speed. Burnt or bad connections can cause this as well.
You can test the blower motor by connecting direct power from a source like the cigarette lighter if you are handy.
Most of the time the lower speeds konk out but the high speed continues to work this is the resistor bank that goes out.
If you bypass the resistor pack and connect the motor directly to the fused 12v supply then the fan should run at maximum speed. If so, it's the resistor pack that's blown: a very common fault on a huge number of makes and models.
I bought used 97 wrangler and no blower .There is resisters for blower motor under dash right side,may have cover over it and is mounted to blower shroud.
