Hey everyone, normally a semi frequent user on the porsche site, but last night my daily driver, '91 300e started giving me fits.

There may be more issues that I have not discovered yet, but here is what is not working now. These items all worked fine when I drove the car earlier in the day.

1) All central locking not working, doors or trunk.
2) Radio powers on, but antenna does not rise and amp does not turn on.
3) Courtesy lights on bottom of front doors don't work
4) Thermostat seems to do nothing, but everything else in the climate control system seems to work. Set at full hot or full cold = same temp out of the vents.
5) The auto down portion of the power windows does not work.

A common ground perhaps or a common fuse/relay?
Any ideas?

Thanks
Derek
