i have a 1995 olds cutlass supreme 3.1L v6 and both of my radiator cooling fans wont come on. the temp over heats. i changed the thermostat and the fan relays and still they don't come on when engine gets hot. could it be a radiator problem or a blown head gasket problem also or likely just the fans would make it run real hot real fast.

Will they come on when the A/C is turned on?

my a/c compressor does not turn on either i also replaced the relay for it but still nothing. i think it might be low so it is just not coming on. but when I press the ac button it does nothing. no fans either.

Try unplugging the coolant temp sensor while the engine is running. This will put the check engine light on but ignore that. The fans should start when it's unplugged. If it does, that will prove the relay system is working.

If it doesn't come on check maxi fuse #3 60A and ECM BAT fuse 20A.

It's in the rear of the engine near the coils.
