Question about 2001 Jeep Wrangler
the book is free,
real books, not fake
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
Fuse PDC #1 to blower relay.
or bad relay
or bad controls.
rtm read the manual, the page is there.
click TJ 02, same car.

If 40A FUSE 1 in the power distribution center and 10A FUSE 8 in the fuse block are OK, the only other possibilities are the blend door actuator, the blower motor relay, the blower motor resistor block, and associated switches.

SOURCE: Jeep wrangler Fuse box
i had the same problem. i drive a 95 so im not sure if it differs from were the fuse box is. look righ above you pedals to your far left. it should be right there. also if you instruments went out it will be a 15 fuse. its a blue fuse. next my panel went out cuz of the wires on my transmission. if yor looking at your jeep at the front. the wires will be on your left. make sure they are not burned or anything. it will be right on the side of your tranny. mind got burned by the exaust so they were shorting. check that is and see if that is what is it. for a temp fix just put some electrical tap around the wires and you should be set for a wile. good luck

The auto shutdown relay in your vehicle is controlled by the computer. If the computer does not see a signal from the crank or cam sensor, it will turn off power to the relay which in turn shuts off power to the fuel and ignition system. Unlike those in many passenger vehicles, it's not connected to an impact sensor. (as jeeps are off road vehicles as well as being transportation, if they had an impact sensor, they would be prone to shutdown when traveling over rough off road terrain)
The fuses to the relay are affected by shorting or overload of any components they serve, or by a problem with the relay itself.

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.

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.

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.
