Hey All,
I have a 2000 C5, the issue is with the dual radiator fans, shouldnt one fan be on all the time? When I click on the a/c both fans come on then. once i turn off the a/c both fans turn off. Even when the temp gets to 225 the fan{s} still dont come on unless I turn on the a/c. Checked the fuses, all ok.
Any ideas???
Thanks

 

Have you been having a overheating problem?
and are you sure the one fan cooling the engine isn't running?
