Agreen Posted October 2, 2023 Share Posted October 2, 2023 ... I know, I know. It's a worn out topic. 1986 XLS model I just got around to troubleshooting them. All other interior lights work, just not the b-pillar ones. That tells me the fuse is good, and that the door switch works. I figured it was an issue with the bulb or the infamous flip-up/down switch with the corroding contacts. I popped the lights out and did a quick power check with a test light. Nothing. The pink/black wire is supposed to have 12v, but it has nothing at all. Multimeter verifies 0v. Is there a connector somewhere that could be unplugged? I have searched this topic extensively, but everyone seems to be having issues with the door switches or the light fixtures. I'm just wondering if anyone knows of a connector to look for before I have to start tearing out all the interior to trace the wiring back?

Agreen Posted October 4, 2023 Author Share Posted October 4, 2023 Hijack permitted for preservation purposes. I just checked that connector. I have power at the pink (pin 5) wire, nothing at the pink wire at the b pillar lights. There's obviously a break somewhere in between. So now I get to pull trim and find it. Yay. There's also a long pink/black wire tucked in along with the light, which I'm assuming would go to the dome light (if equipped)? I don't think mine came with a dome light, so I'll leave it alone.

schardein Posted October 4, 2023 Share Posted October 4, 2023 What you may be seeing is the wiring for the optional cargo light. That wiring was always present (whether the light was optioned or not) up until about 1990. Then it would only be there if it was factory optioned. There was no optional dome light. There were the under dash courtesy lights, and the b pillar lights. It would be helpful if you added some info about your rig to your signature line. Year, engine, transmission type, at a minimum.

Agreen Posted October 16, 2023 Author Share Posted October 16, 2023 Finally got back to it. I had to end up pulling all the panels up and inspected the harness from C118 all the way up to the first light. I never could find a physical break, so I found an old wiring harness in a bucket in the garage and stripped a pink wire out. I ran the wire along the harness, zip tied about every 12", and tied it in at both ends with a bare crimp and heat shrink. One light works, the other had a bad bulb. It's on order, but I have light! Thanks for the help. Link to comment Share on other sites More sharing options...
