TJ Wrangler Auto Electric Help Regarding The Blower Fan?

Hey, can anyone please help?
My demister blower fan on my 03 tj wrangler has stopped! No fan on any speed?
I have checked all the fuses and they seem o.k?
The fan switch, resistor, blower motor are all o.k?
I noticed that there is no active line on the wiring harness under the dash?
I mean when I pull the harness apart at the junction behind the glove box the part that runs to the blower and the switch is dead? No power coming through? I replaced the switch and still have the problem?
I located a main fuse running off the battery line and it is o.k?
The harness wiring dosen't look cooked, it looks as new?
The problem seems as though it could be just a fuse but they are all o.k.
Well at least the ones that I can see?
Could I be missing one somewhere not visible?
Has anyone had a similar problem?

I have an 01 and the fan stopped on it. The fan connector on the motor under the hood rattled loose. According to the local dealer, that is a common problem with soft tops due to the fan being on "Hi" a larger percentage of the time.

I have a similar problem. Sometimes when i crank my 2004 up, the airbag light comes on and at the same time the airbag light comes on , the blower motor for my a/c doesn't work at all. I don't know where to start looking.

Off the top of my head. Loose plug/wiring on the motor, bad ground, or fried motor. Anything else would have to be traced with a schematic.
