Thanks Jas2wa.
Just ot answer your question Cal. No thw 2 aux fans do not come on at all. even when the blue switch is pulled. |
Check fuse 7. Try jumpering the pigtail leads from the red pressure switch at the A/C drier (key on engine off). That should give lo aux fans. If no fans, tap on the fan hubs to make sure they're not stuck. If still no, bring jumper from battery + to the two-wire side of the series resistor located behind the driver side headlight. That bypasses all of the aux fan circuit except the wiring between the resistor and the fan motors. If still no, the wire between is bad or both fan motors are bad. If that turns on the fans, you've verified that the fan motors are good, the problem is upstream in the circuit. Check the blue and green relays that each have a fuse on top that are discussed earlier in this thread. I think the relays are located in the relay box at the back of the main fuse box. These relays power the lo and hi fans.

I know a guy here that writes instructions just like that... |

I swiched the relays as they were reversed.
So ONE of the fans started to work after tapping it a few times. But a few hours later it doesn't turn at all anymore!? |
wouldn't you know...
I have come full circle with my cooling issues. Per the dealer, the high pressure switch that turns on the twin electric fans is bad, and the fans themselves are toast, too. One turns (but apparently not fast enough) and the other is dead.
$700 for the entire twin fan assembly?? Are these indivudual fan units replaceable themselves (for what looks to be about 140/each)? |
