i know that on a 92 lumina you can turn on the cooling fan by grounding one of the prongs from the relay. but on my 94 lumina I'm trying to do the same thing but when i checked the relay has 5 prongs:confused: so can anyone please tell me which one to ground if anyone has done it

If I unplug the coolant temp sensor and start my 96 the fans will come on.

The '94 should be OBD1 which means you can jumper into diagnostic mode with a short wire, a paper clip or one of those metal keys from the auto parts store. this should activate your fan(s).
