2001 Grand Cherokee relay cooling fan
I have a 2001 Grand Cherokee, and the radiator cooling fan isn't working, but if I conect the fan to the baterry it works propertly, I think that the fan relay is broken but I don't know where is it.Can some body tell me please the relay fan location?
Thanks.
Thanks.

I suspect an engine temp sensor may be the issue. This sensor is what reports the temperature to the computer, this the computer turning on the fan when required.
Is the vehicle overheating?
Some times, it takes a scan tool to determine the true coolant temp. You may want to see what it is reading.

Yes it is overhaeting, do you know where are the sensor temp
and the fan relay, I think these are the two posible reasons.

HAVE FUN......The relay is underneath the right front headlight assembly. Remove the grille, Bumper cover and headlight assembly. When the Headlight housing is removed, Look carefully at the plastic framing. There will be a "Dimple" in the plastic. Drill a 1/2 inch hole thru the dimple. In the hole will be a 7 mm bolt. remove it thru the hole. Remove the bolt to the left of it , between the headlight and bumper support housings. Pull the relay into the engine compartment and lift up....

Thank you very much.
Your welcome, But dont expect a grin when your cursing at me.....
You are undertaking a royal pain of a procedure.Take your time, be patient, and it does come out.....
You will likely find burned terminals at the connector. If so, it would be a really good choice to replace the fan also. A Worn fan can draw excessive current, and damage the new parts youve just installed.

To answer the current draw question....A spark is somewhat normal, Burning a hole in your finger tips isnt. If the Relay connector is intact, I wouldnt worry too much about it. The fan is much easier to replace than the relay, but Very pricey. If I remember correctly , the cooling fan is protected by a 40 amp fuse, so to overload it is pretty difficult, But as mentioned, This will all hinge around what the connector looks like when it comes out.
