    I have a 2002 Jeep Grand Cherokee. After I replaced the power window motor (every two years...Thanks Jeep!), my turn signals and air system (heat/AC) stopped working. Turns out fuse #20 was fried. Popped in a new fuse and the turn signals are back! BUT, the air still doesn't work. AND, now the turn signals only work when the car is in Drive. Ha! There's definitely an electrical issue at play. Any thoughts/suggestions are greatly appreciated! Thank you!

    *UPDATE*
    Just checked, fuse 20 (air system and turn signals) is blown again, BUT turn signals still work when car is in Drive. To test, I put in a new fuse and -pop- on start up. Something is causing a short.

    Before replacing the fuse again the issue causing the short needs to be found. Could be rodent damage or failing component or wires.
