The trunk light in my AP1 does not work. The stock bulb would work randomly, so I bought and installed a new bulb, but the light still doesn't turn on when I open the trunk.

Note: when I first installed the new light, it turned on ... but since then, it never turns on when I open the trunk! None of the other lights in my car are having issues. I visually inspected the trunk light housing and it looks clean/no corrosion ...

Any help/advice???

 

Did you blow the fuse? Check under-dash fuse #24.

 

^^

 

Fuse 24 also supplies the dome light with power so that can't be it, assuming that is included when you say that none of the other lights are having issues.

I would say it would be the trunk lid switch.

 

Yup, it was the trunk lid switch. The trunk lid switch is completed when you unlock and open the trunk by touching what looks to be a copper contact piece. I had to play around with it a bit, but eventually I was able to clean the copper piece and get the lock to move more freely. Thanks for all the suggestions!
