I have a 1988 Porsche 944 nonturbo. The fans continue to run even after the engine is off. I have replaced the temperature switch and the fan relay but the fans continue to run. I am not sure what else to check or replace at this time. I would appreciate any ideas or thoughts?

If you remove the fuse do they turn off?

It may be a/c related, possible a/c high pressure switch.

No, once the AC is off, the power to them should be off too. I'm wondering if there is a short sending power to them all the time or if this is an ignition switch issue.
