My 99XJ has the CEL on due to a P1491 error code. The Fan Relay circuit has a problem.
I understand this relay (below the pssngr headlight) is for the AC supplemental electric radiator fan.
1. I cannot get the fan to turn by jumping from a 12v source to the blue wire leading from the Dorman fan relay connector to the fan motor.
2. I installed a new fan relay yesterday. Today the relay appears to have a baby bump.
3. I did not test the old relay before discarding it (dumb me).
I assume that the electric fan then needs to be replaced?
What would have caused my new relay to swell up in the center of the relay in one day's use?
