Recently my AC quit on me. No warning at all. It worked on the way to school then after football practice it would not come on at all. Even if I turn it to heat and put it on defrost I still get nothing. Where should I start the trouble shooting process? On a side note it seemed like my defrosters were always on when I had my AC on. Any ideas what caused this?
 
If it doesn't turn on at all on any fan speed, the likely cause is a blown fuse.
 
If not a fuse pull the center section of the dash and the hvac control panel out. Look at the fan speed selection switch (on the back side where it plugs in) There’s a problem with Jeep design and they have a bad habit of melting down.
 
Checked the fuse and it’s good. Checked the selector switch and it looks fine. How would I go about testing the relay?
