I have a 2000 Jeep Wrangler Sahara. 1 year ago, the heat and ac would only work in the maximum position. I took it in to be fixed, and they said that there was something wrong with a component of the inside of the dial/switch. Now 6 months later, the heat/ac won't come on at ANY setting. Blower/fan doesn't switch on(whatever that is . . . I'm not very mechanically savvy!) nothing! Any suggestions as to what this could be. Many Thanks! :)

Blower motor would be my guess, but would return to the same place and have them check it. Perhaps the heater control module? went bad again.

I'm not an expert but I had the same exact thing happen to me in my wrangler. The fan speed switch is plastic, and it melted after years of use. First none of the lower settings, then nothing at all. The leads had shorted causing the switch to stop working and blowing the fuse for the blower. Replacing the switch and the fuse did the trick.

Suggested Repair

Check the blower fuse and replace the plastic fan speed switch if it has melted or shorted. If that does not restore the blower, have the shop recheck the blower motor and heater control module.

Conversation Summary

The owner of a 2000 Jeep Wrangler said the heat and AC previously worked only on the maximum setting after a dial or switch problem, and later the blower would not run at any setting. A service writer suggested the blower motor or heater control module. Another owner reported the same failure from a melted plastic fan speed switch that shorted and blew the blower fuse; replacing the switch and fuse fixed it.
