Help: 97 TJ Wrangler A/C / Heater Blower Problem
 

Good Morning,

I am trying to narrow down what may be wrong with my A/C /Heater
Blower.
The problem first started with just the high setting not working. All
other settings were fine but when on the highest setting it would stop
blowing. IT's like it would just cut off. I could still feel the warm
or cold air trickling out but no blowing, back to the first 3 settings
and all was well.

Now all of a sudden none of the settings are working. The compressor
kicks on and cool air trickles out but the blower won't kick on.

I tried the relay behind the glove box that did not work. I just order
the resistor that is by the pass. floorboard but it won't be here for
a few days.

Is there anything I can check to see if the motor itself is bad or
could it be something else that I need to change / check.
Thanks for any advice / help!

There is a bad batch of switches out there that can cause your symptoms.

The switch is less than ten bucks at the dealer, but you have to get the
guy to dig for it in the parts list, he will want to sell you the whole
panel.

It was posted here that it is best to take the Jeep tot he parts store
so you can test it because some are bad right out of the box.

You will want to inspect the plug for damage also.

Thanks for the quick response.. Is it the switch connected to the back
of the Climate Control panel? I took that off and took it to Auto Zone
but they couldn't match it. I also called the jeep dealer and (like
you stated) they claim to only sell it as a unit.
Or are you talking about the resistor under the motor?

Thanks Again!

The switch itself. The dealer does have it.

If not, the wreckers do.

A multimeter should be able to test the switch. When mine went it was
obviously burnt, it let the smoke out big time, but that was a Cherokee.

I think someone posted a part number for it a while back, maybe Google
can find that.

There are also some ground wires that bolt to the back of the dash panel
that also can affect the heater switch when they come loose.
