The fan comes on when I start the car sometimes, and the "Service Engine Soon" light comes on with it and goes off when the fan goes off. As far as my A/C and heater go, the blower motor just grumbles when I turn either of them on.
Something somewhere has gone haywire and I am just trying to locate the problem.
Whatever it is, it is causing my battery to drain over night, so I checked ( unhooked negative battery cable over night) and it is not my battery. I hooked it up this morning and she started right up, but so did the fan. Could this be the switch? And where is my A/C compressor switch located? I have checked all of my fuses and they are good. Where would you start, and how would you check this out? I can not trace the wires (LT Blue and Black) from my radiator fan because they are running to a much larger wiring harness, and into the passengers side firewall.
