Hi all,
I've got a 02 Jeep Cherokee that has had an overheating problem. Basically what happened was that the fans did not turn on. I replaced the fan relay and it worked for several months. Now, they wont turn on. Could it be the ECU? If the engine still runs, would that rule out a faulty ecu when the fans dont come on???? Any help is greatly appreciated!

A 2002?

He prolly means 92... buttuns are kinda close to each other.

I'm sorry, its a 2002 Jeep Grand Cherokee Laredo...

Moving to the Grand Cherokee forum for you.

It sounds like the fan relay has gone bad. It's an easy fix, and there are numerous posts here about similar issues. Do a quick search and you'll find them.
