Default Cabin - No Power

Hi everyone,

Got myself copies of the FSM and Electrical Supplement for my 1984 C4, as well as the standard-issue owners' manual and am going to start hunting electrical problems, armed with my digital multimeter. But I wanted to see if the symptoms I'm having ring a bell for anyone who might be able to recommend where I may want to start troubleshooting.

Right now, I have no electrical power in most of the cabin. So, no courtesy lamps when I open the doors, no wipers, no cigarette lighter, no power going to the recessed rear hatch button in the driver's door, no passenger visor mirror lights, no power locks and no power to control the left sideview mirror. I also have no courtesy lights when I pop the engine hood either. The radio works, LED dash panels work, the right mirror control works and so do the power windows.

Based on this, does this sound like I have a common problem for all these symptoms, i.e., is there a wiring harness for which all these systems are powered that somehow may have disconnected?

I'm off to go read about fuses and wiper motor covers.....

Thanks friends,
Chris

Update: So I found the fuse that handles most of those issues and tested it to find out it had indeed blown. However, upon replacing it, I only regained the door lock power and the cigarette lighter power. The door chime, courtesy lights and vanity mirror light, and driver door hatch release switch should have all come back online too with that replacement, but didn’t.

This ring any bells for anyone?

The courtesy timer may have burned out.

Updating this thread, upon removing my door panels to address other issues, I came to find out I have no door courtesy lights because the previous owners removed those fixtures but left the white plastic covers in place.

I'll replace these all later.
