the cooling fans on my 1997 corvette dont run. I have unplugged the collant temp sensor in the block and jumped the plug but they still dont run. I have also tested the relays under the hood. Any ideas

If not, test the fan motors themselves next.

AC wont run either. I assume it is because the fan wont run. AC comes on then goes off immediately.

Have you ran power to fans see if they work? PCM controls AC operation also
