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.

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.
