Any of you Jeep guys know how to fix an in-op coolant fan! It s a 1999 gr cherokee 4.0 L ...I replaced the temp sensor...oops...didnt help.....I disconected fan connector and applyed 12v directly and the fan works fine.the fuse in the power distribution block ( green 40) is good. do you know where the fan "switch " is located or does the PCM turn the fan on and off! i heard this is a common problem! any help would be appreciated!:? :?
