Hi I have a 1996 Ford Windstar 3.8l and the radiator fans aren't turning. I took it to a mechanic and he said that the CCRM was bad so I replaced it along with a whole new fan assembly, since my radiator fan motor was dead. After replacing them, still no luck. I ran a wire from my battery to pins 3, 4 & 8, 10 on the CCRM to check if the fans would run and they did. So next I checked the coolant temp sensor and saw that it had been corroded so I changed it w/ hopes that that was the problem, but still not it. Finally I checked my PCM as well as I could. I ran wires again from the battery to pin 46 (High speed fan output to CCRM) and the fans ran, but when I put power to pin 28 (Low speed fan output to CCRM), nothing.
Forgot to mention that I've tried idling my car for about 15-20 minutes while reving waiting for it to heat up and no turn of the fans. But when I turn the A/C on both fans will kick on, after the vehicles running a little above average temp on the gauge, and will only be on for about 5 seconds then shut off for a couple minutes.
Please help! I'm pretty much fed up with it by now, but willing to try/check out anything.
