1988 911 Cab Clock Radio Interior Light

[rdoine]

I just replaced the interior light fixture because it cracked. While waiting for a replacement part, the clock and radio stopped working. I have replaced the light fixture but it does not turn on and the clock and radio still do not work.

I've checked the fuse and it seems to be fine. I switched the fuse with one from another working circuit. I still do not have a working interior light, clock or radio. I'm not sure where to look next.

Does anyone have any ideas?
