1998 Jeep Cherokee Sport v6 w/ 122+k miles on it.
2 years ago the blower stopped working in my car, and my father in law fiddled w/ the fuses and suddenly it was fine and has been up until yesterday afternoon. It worked on the way home- turned off the car to run inside and change and when I turned the car on again the blower was no longer working. Bought brand new fuses and replaced all of them in the box- there is cold air, just no blower. What can it be?

Did the blower fuse blow again? I just had a similar problem in my jeep, but the blower would only run on high - lower speeds dead, fuse ok. I pulled the dash-mounted control unit out, the switch was toasted, the plug-in connector was toasted. Turns out the problem was a "Blower Resistor" block located under the dash, passenger side. When the resistor block failed the blower would still work on high because high speed was directly wired to the 12vdc power source and completely bypassed the resistor assembly. New resistor block - $11.00 at Jeep dealer. New Switch - $20.00 at Parts store. Switch connector - $3.00 at auto salvage yard - had to cut my own connector and wire leads out of a non-working jeep, then butt-splice onto my wires. Jeep doesn't sell just the connector, it's part of the dash wiring harness - $1000.00. Hi-ho, Hi-ho, off to the junk yard I go. Good luck, and post what you find/fix so the rest of us can learn. Thanks!
