The fan for the climate control system in our 2002 Jeep Grand Cherokee Limited runs and then stops and then comes back on and continues to do this on it's own. Any suggestions?

Asked by Aug 20, 2014 at 08:10 PM about the 2002 Jeep Grand Cherokee Limited 4WD

Question type: Maintenance & Repair

Fan turns itself on and off as we drive, no matter what position the fan control is turned to.  
Is there a relay that could be doing this, and if so, WHERE is it located?

The fan is controlled by the HVAC module, there are relays in the power distribution box under the hood. There could be a problem with the control head, but you will need to run a code check on the HVAC to verify.
