The quick way is to remove the headlight on the passenger and with a right angle carbide blade, cut a 4" X 4" hole in the bottom of the plastic shroud under the headlamp.....center it and do not let blade penetrate more than 1/2 inch. Remove piece and the relay is right there...........remove two retaining screws and unplug it and install replacement. Cement removed piece of plastic with silicone rubber caulk..............total time to fix mine was under 30 minutes as opposed to 4.5 hours of flat rate manual time.

The fan relay is stuck on.The relay is located under the passenger side headlight and requires removing the front bumper to get to it.You can unplug the fan as a way to keep the fan from running when the car is off, but you should never run the car with it unplugged.

No heat or ac blowing 2003 jeep grand cherokee


If nothing is blowing at all then you need to check the fuse, check voltage at the fan by turning on the switch if no voltage then the switch is bad, if voltage and no fan then the fan is bad.

Electric fan on my 1999 jeep cherokee classic wont shut off after you turn ignition off what could be the issue?


the relay is maybe sticking.
or there is a call for cooling when the engine is off.

if the fan turns off after a min or two then its ok.

if the fan stays on and will not trun off ever even after 30 mins then the relay is staying on and needs to be taken out and replaced.

2003 grand cherokee cooling fan not coming on , replaced thermostat. How do I determine if it's the fan relay?


the fan relay is very hard to get to! it's under the right hand side head light assembly.
you need to get to it to check the power to and from it when the engine is at the operating temperature.
a repair shop with proper equiptment can use a scan tool to demand the fan to turn on. if it does not turn on then the relay is bad, with condition that the fan is known good

2003 jeep grand cherokee radiator fan doesn't turn on


Disconnect the fan plug and hot wire it to the battery if the fan dosen't run, replace it. Otherwise, check the relay. The system operates by the temp sender sending a signal to the computer that activates the relay that turns the fan on. Fan should also come on with A/C.

OVER HEATING ISSUE!!! 2003 JEEP GRAND CHEROKEE


Since you added coolant, now it is time to check the fans. If the fans do come on, than your thermostat needs to be replaced, Should be done every 4 years anyways.
