I really appreciate. > Michael in San Antonio > 91GL Weekender AT 2.1L 'Gringo' Michael, I'm not sure what you mean by "2nd fan." You also mentioned a very loud fan with the air conditioner on. When the air conditioner is on, the radiator/condensor fan runs at high speed, I think. Mine does, anyway, just as it does when the engine is getting hot. The radiator fan on high speed is very loud. I'll leave the overheated wire to experts, but it doesn't sound good. Fuse didn't pop? Maybe should? DMc -- David McNeely |
