91 Jeep XJ with 4.0 and A/C
The A/C clutch won't engage and the aux engine fan won't engage.
Done so far:
The relays, fan and A/C clutch are fine have traced two wires that go to to the ECU Blue/pink for aux fan and blue/red for the A/C clutch. If I ground the wires the clutch and the fan comes on. So I think everyhting is OK after the ECU. My next step is to start checking inputs to the ECU...
Anyone got any ideas?
