HVAC no blower fan on 97WJ

[spanky]

Fan stopped a few months ago, ckd all the fuses/relays which were good. A few days later the fan miraculously started back up. Now that it is cold out side the blower fan does not work in any setting regardless of the other two knob settings on the climate control panel. No pwr at the blower connector. Any suggestions? Common problem?

I think that one is the same as the one in the TJ, I had the connection at the back of the switch melt. I have read of others having the same problem. I pulled the controls out, cleaned the connections and dielectric greased them and have had no problems since.

Mine is the three rotary knobs in a row.

Pull of the connector and see if it looks burnt.
There are alot of amps running through that connector at high speed it can cause a problem.
The Chevy Suburban had the same issue, once you rewired the connector, no problem.
