Anyone know where the cooling fan relay is located in a 1999 Jeep Grand Cherokee?  
  
  
  
 I’ve looked in the fuse boxs under the dash & next to the battery.  
  
  
  
 I also followed the cooling fan wire back to the fuse & didn’t see it.  
  
  
  
 Could it be named something less obvious than Cooling Fan Relay?

Here is a picture of the relay. It shows the relay having two mount holes.

Thanks guys, this was great advice.

I wasn’t previously aware that [autozone.com](http://autozone.com) had repair instructions.

Removing the all the facia, grill work and headlights was a bit of a hassle but the job was done in about 2 hours and replacing the relay fixed the problem.

The original problem was that the fan wouldn’t stop running without disconnecting the fuse or battery! The thermostat tested okay so i was left to assume it must be the relay.

- thanks again, carbonblaster
