2G Radiator Fans will not come on!

[OneFastEclipse]

I put a new fluidyne radiator in and the drivers side fan will not come on. I do not have the passenger side fan in because it will not fit. Could this have anything to do with it? All connections are good. I checked them over like 50 times. Any ideas?

how do you have it hooked up?

What you mean? I have then plugged in the stock connections. They are the stock fans.

I don't know..I hope you find out. My passenger side fan is the only one that comes on. I just figured drivers side was blown or it only kicked on at a certain point.

the driver side fan is only going to come on when the a\c is on. the passenger side is the one for the motor. your fans are working correctly.

The AC fan will come on but the radiator fan (drivers side) Will not work. The fan itself works cause I tested it on the AC side and it spins. It has to be a connection somewhere that goes to the drivers side. What could have been tampered with during a radiator install?

there should have been a sensor on the bottom of the stock radiator, it is a temp sensor to tell the fan to come on at a certian temperature. if that is not in or is bad, the fan will not come on because it thinks it is still cold.

On a friend's car, it was a bad relay.
