I have a 1987 944S with all items controlled by fuse #28 (reverse lights/power mirrors/rear wiper/etc.) non functioning. I have checked the fuse and it is fine. Is there another fuse/breaker which I am overlooking? Any advice is appreciated.

Thanks

 

Have you tried replacing the fuse anyway. i have had problems where the fuse looked fine and tested fine but was shot. Also have you crawled under the dash and checked the wiring plugging into the fuse box? might just be a loose/bad connection.
