the guy just didn't want to get his hands dirty....we NEED a solid 1/0 awg Battery cable to the chassis ground connection....undo the lug and wirebrush the lug by holding it with a pliers and scrubbing with the wirebrush...and the chassis to let a full 300 amps or more through that spot....a restored system ground will allow the lights to work...the ECU to dial into the right values and sensors wake up and start helpin'~

By fans do u mean the cooling fans for the radiator assembly? I think what the fellow was trying to pin it on is the ignition wire harness. You will know if this sounds familiar.... Heater/ air cond. fan not working on all fan speed settings, rear defrost probably dont work, info center fading out. Headlights will dim and go out too. Its about 2.5 hours, I replaced one last summer at night. If im on the wrong tree let me know. MP
