post icon Chevy Cruze radiator fan still running drains battery Sign In

Last night when turning off my car i noticed that the radiator fan was still running, i brushed this off knowing that sometime thats normal with cars. This morning my car was completely dead, I got some jumper cables and when charging the car the first and only thing on was the radiator fan, i let it charge for some minutes and drove the car around for a bit. When I turned it off the fan was the only thing running. Help
The link below shows the fan running when off and a small leak, maybe the leak is the problem

1st suspect is a relay. They can about weld points shut so item stays on surprised this new didn't think anything kept cooling fans on when key/ignitions are off? Are you sure it really off?

Yep keys out and all. The fans were running when turned off, later about an hour later I went to go check on it and the fans were still running.

Fans should have a relay likely in under hood box and marked. Pull it out at least to verify they shut off. It's that or into disconnecting battery or you'll kill that too going dead also kills batteries do something so it's not twice the work or worse still think a relay is most common for that,

This is not going to be easy to diagnose. This is a three speed fan that uses 5 different relays in the circuit. Maybe you can identify which feed is staying powered.
