i have a 93 z-34 my fans don't work either but i took the #1 relay out and checked to see if the relay was getting power and it was with a gauge but not with the test light now also the fans on mine will come on if you use the bypass feature to check for trouble codes but i don't know enough to answer your Q or mine for that matter
Check the relay.
Remove the bottom radiator hose from your 1995 Chevy Lumina radiator. Put a water hose in the top of the radiator. Allow the water hose to run. Keep the water running until clear water runs out of the bottom of the radiator.
There may not be one, My 2000 Lumina has a plug on the lower drivers side of the radiator that can be replaced with a petcock. Rather than do this I removed the lower radiator hose to facilitate flushing the cooling system.
where is the drain plug on a 99 Chevy lumina where is the radiator drain plug on a 99 Chevy lumina I am not completely sure about the 99 but I drive a 95 lumina and the radiator drain plug is located to the right of the radiator (if you are looking under the hood) and at the bottom of the housing for the radiator. Mine is white in color.
where is my cooling fan relay controll circuit located in a 1997 Chevy lumina, 3.1 engine
the thermostat will make both fans become idle if it is not opening. this happened to me on my 95 3.1 lumina
Remove the bottom radiator hose on your 1996 Chevy Lumina radiator. Put a water hose in the top of the radiator. Allow the water hose to run until the water draining from the bottom of the radiator runs clear.
depends on the engine size and the transmission type.
