Question about 2000 Jeep Grand Cherokee

2 Answers

Can't locate the cooling fan sensor or relay.

I'm helping a friend with her 2000 Grand Cherokee. The engine fan won't come on. The fan works when jumped to the battery. The 40 amp "fuse" in the fuse box is good. There is power at the fuse box. I'm assuming a sensor or relay is bad. Where are these located?

The radiator fan relay is located behind and slightly lower than the r/f headlamp.best way to get to this is by removing right side of front fascia out enough to get behind it. this will give you acsess to the relay.i work at a jeep dealer and have done this many times.

It's usually an issue with the relay which can be found one of two ways. You can either remove the front grille, bumper cover and support brackets under the cover, or you can remove the right headlamp assembly and smack a hole in the plastic underneath it with the ball side of a ball peen hammer. I start right in the middle of where the headlamp used to be and peek around to get a more accurate idea of where it is. Then I smack another hole directly above it and unbolt it from the frame. When you put the headlamp back in, it will cover the holes you just created as long as you don't get too hammer happy.

This is controlled by a relay module .The location is under the passenger head assembly.Dumb location i know but that is were it is at.There is also problems with the fan assembly it self .Test for power on the red wire at the fan with the ac on this will make the computer tell the relay to start the fan.

My 2000 jeep grand cherokee is overheating when i drive less than one mile and the coolant light is going off. i replaced the thermostat and checked the coolant level (which is fine) but it is still...


replace your cooling fan motor relay because if you dont eventually your radiator will explode and this will cause your engine block to crack and then if your fan isn't blowing the engine will continue to overheat and the engine will seize and then you need a new engine. A cooling fan motor relay is around $30.

Radiator fan not working replaced relay,temp


You didn’t mention replacing the temperature sensor located on the block in the path of the ‘cooled’ coolant.
I can’t tell you any closer where to look for it since you didn’t specify which engine you have.
This device is a solid state item called a thermistor.
With the air temperature around 77 degrees F and a 'cold' engine, it should measure about 10,000 Ohms and hot, around 1,200 Ohms while disconnected from its mating connector.
With the ignition on, and the connector disconnected from the sensor, you should measure about 5 volts coming from the ECU.
If this has failed, the ECU is not getting the right info back from the sensor and doesn’t know if the fan is needed or not.

Over-heating


When the engine is at operating temp check the electric cooling fan. If it is not moving then i would check the fan relay which is located under the right side headlamp. 9 times out of 10 this is the problem
