Hello,
I have been having trouble with my Lumina heating up for a while now. About a month ago I changed the thermostat and flushed the cooling system. That helped for a while, but eventually it started heating up again. I realized that the cooling fan would not come on till the heating gage was all they way on RED. So I came to the conclusion that for some reason the fan would not cool the engine, until dangerously HOT. Today I tried to check the relays and see, if i can find the problem. I checked (Fan Cont #1) by removing the relay and creating a connection by placing 2 (V) shaped metal wires and both fans started working. I repeated the process on (Fan Cont # 2), but unlike the first time there was a spark and when i tried to start the car it would not start. I realize i must have caused an electrical short some where, but i'm not sure where to start. Please help.!!!!
