Ok, Your fans actually have power and they work due to your A/C test. I don't know why they don't come on in "norm" A/C but I will tell you that if you have a BAD coolant leak and you're not bleeding they system, your fans may not be coming on due to an air-bubble in the system. Your themostat and otterstat switch may be fine but the system is air- bound and the coolant isn't circulating. Try: 1. Running the engine until hot, feel supply-side (driver's side) coolant pipe down by the otterstat switch. Is it cold? If so, you're not circulating. Bleed air out of the system with the bleed screw on the thermostat housing. Better yet, buy John Hervey's constant-bleed kit. 2. Jumper the otterstat wires together and make sure the fans come on. This will eliminate a wiring problem at that end. 3. You could remove the otterstat and boil it in a pot of water with an ohm-meter attached. Make sure it clicks and you read a "short" or zero ohms.

For those without the workshop manual, the compressor switch was on "OFF" and the fan speed was on "0". If I turned the compressor 1 dial to "max", the fans WILL come on. If I turn the compressor knob to "norm", the fans will turn OFF. IF I turn the compressor knob to "Bi-level", the fans come BACK ON. For kicks, me and Dmc83n99 experimented with his control settings. On "Max", "Norm", and "Bi-level", the fans were on all 3 times. > > DMC-Houston suggested the following: > > 1. Have the car sitting cold > 2. Fill it with coolant > 3.

Is it the first one listed for about $129.00? If so, I'll check my car and see if I have anything like that. > > Point #2. Dmc83n99 suggested to me the overheating problems (resulting of course because the cooling fans aren't coming on) may be the result of a failing thermostat. Now the only thermostat I know of on this car is the one featured on C:12:01 or http://www.usadmc.com/dmcstore/ViewPage.asp?PageID=12#19. He is sugguesting that the thermostat is failing to register, causing the cooling fans not to activate, causing the temperature to increase to dangerous overheating levels...and possibly also being the reason the idling is so high...this is of course all just suggestions. > > When I first received this car back on Nov 11th, the cooling fans DID come on automatically by themselves while the car idled..this does lead me to believe that the thermostat may have simply failed. I have a feeling this car hasn't just sat for months; I think it has been sitting for YEARS, and now that this car is finally being driven - parts are breaking due to the sad fact they've been disengaged for so long that they're brittle and are breaking easily. > > > --------------------------------- > Do you Yahoo!? > New Yahoo!
