92 Grand Prix radiator fans

[92GrandPrixLE]

Short story: Bought inexpensive car for kids first vehicle & fixing up nicely to make safe...Latest issue, got a call from wife that the car was overheating w/ a/c on, she turned it over to heating & it dropped down nicely. When I took a look at it I noticed that the driver side radiator fan would cycle on, but not able to witness passenger side fan running. Is the passenger side an a/c condensor fan only? Do the 2 fans simply run @ different temps (driver side first, passenger side second)? Any quick tips to troubleshoot? Thanks, Dave

check the grounds. poor ground could cause this

Check the ground where? At the plug into the fan?

not sure since i'm not sure how that fan would be wired but trace all the wires and see if any are frayed.

buy one of those. It helps a ton with electrical issues. Or run a jumper wire from the batter to the fan to see if you can get it to turn on.

Do the two fans ever run independantly or do they always run simultaneously?

i had the same problem, I have a 99 grand prix gt and i noticed that when you turn the ac on both fans run! but i have never witnessed my fans working without the ac on.
