I have a 2004 Jeep Grand Cherokee. A couple days ago the blower on the ac/heater stopped working (the light on the AC button doesn't come on either, which maybe connected to the blower) and along with that, my turn signals now won't work. The turn signal lights (both on the dash and outside) do work when the hazard button is on though. I've checked every fuse I could find underneath the dash and under the hood. Then yesterday it overheated, which makes me think the radiator fan won't run either, becuase if i keep it about 45mph it stays cool until I stop. Are these components tied together somehow? Is there a shared relay or something?
Fans usually have their own relays my car has two. Completely different systems would not be connected. Look in your owners manual there may be another fuse box. My daughter's car has 4 fuse boxes.
