Question about 2002 Jeep Grand Cherokee
You need to find out if the fan relay is good, pull the relay out for the fan and check to see if you are in fact getting voltage to the fuse/relay box at that location. But you could have a bad temp sensor, the fan would not know to kick on at a certain engine temperature. before replacing parts, it's best to find out for sure you're not losing voltage somewhere. The parts are not too expensive but no need in changing good parts. It's hard to really pin point the problem with out being there to test. Good Luck
