Wrangler 2003 w/ an interior fan problem
 

The fan for blowing air inside my Jeep has been slowly degrading
performance. At first I though it was me. But as of this morning, the
only cycle that works for blowing air is the highest setting. The
three lower settings do not turn the fan on at all.

Does anyone have any information they can share that would help me
understand what part my be going bad or is bad or how to fix it?

Thanks
Ig

That is usually the resistor pack that lives in the bottom of the
passenger side footwell in the heater box.

There also seems to be a batch of defective switches out there, but
usually that craps out high as well. If it is the switch, you can just
by it, you don't need the whole cluster.

Re: Wrangler 2003 w/ an interior fan problem
 

I believe the slower speeds are regulated by a resistor pack with the high
speed going directly through the switch. In the WJ it is below the dash
behind the glove box.

I'm sure someone will chime in with the exact location for your model/year.

Mike knows a lot more than I do on the subject. Had I seen his post I
probably wouldn't have replied....

I've not had the problem but I've heard the hardest part is contorting
yourself upside down in the passenger seat so you can see what you are
doing.... To some of us it is more difficult than it used to be a couple
years ago....ahem....when we were young and skinny.

This is not very hard to replace at all !! It is located below the
glove compartment and is held in with two screws.. It's actually in the
air stream of the blower to help keep the resistors cool.. I paid less
than $15.00 and didn't need to turn upside down - did that alot on
airplanes but not yet on my Jeep... The resistor block is simply
several resistors protected by a cage - half the size of a soda can.
Also, I would clean the connections at the motor under the hood. I
found mine corroded and once cleaned, made a big difference....

It's kinda hard if you only know it's in the passenger footwell area.
I disassembled several interesting parts of the heater box, little
motors driving geared cams, etc., before discovering the resistor pack.
On my 2002 (with AC) it's a black credit card shaped powder coated
gizmo with some wire strips imbedded in it. Looked fine but sure
enough one strip was an open circuit.
