Sat. morning the car started fine. On the way to our once a month car guy hangout I found that the sunroof, windows, mirrors, wipers and fan were inop. Checked fuses- none blown. All other electrical items OK. On the way home a few hours later everything suddenly started working.
Is there a common relay for all these components?

 

Could be a wiring harness issue. What year is your car? Early 993's should have been recalled to get this replaced.

 

Check your ground on that circut.

Car is a '97 so I don't think it's the harness. I'll look for a common ground/relay.

 

There is no common relay for all those. R21 for the SR and R22 for the windows. The numbers are marked on the inside of the relay/fuse lid. I would pull each relay out, clean and dry the contacts, then reseat each. I thought my WS washer relay was out, did the above and it worked again.

 

I feel like an errse for asking this question. But when you say check the ground, how do you do that?
