I have a 1995 Chevy Lumina that is overheating. Both fans are not working when it reaches the point of overheating and the car begins to run rough. I dont know if theres a thermostat switch that has gone bad or if the relays are bad or the fans themselves.

 

check out the post on 98 lumina overheating I am sure they will tell you the car is same generation as yours and the answer will be found there,,,the fans should be working..theromostat might be shot... if the fans dont go on before it hits the red line then you have either bad fans or bad relay switches... maybe bad wires you will have to start with the theromstat first unless you check the wires for power to the fans ,, and or jump a direct wire from battery to fans to see if they work,, thermostat is cheap and easy to start with,, take it from there,, testing the rest,,
