I have. 94 cherokee 4.0 i6
it heats up very fast while driving and idling. 1 of my fans does not turn on. I tried jumpering it and the fam came on. Fan works just can’t figure out the problem. Is the relay bad, faulty wiring any help would be awsome

 

How hot does it get exactly? The electric fan should come on at 218* F. Optimal operating temperature is about 210* F.
