Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

5 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 1 adjusted by outcome qualification.

1 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

In my 02 Boxster S the instrument and license plate lighting is not working. They are both on fuse A5. I have checked that fuse and it looks OK, but those lights are not working. Anyone had a similar problem?? Any suggestions??

POST 2Original post

Fuses can look ok but still not be right. You can check continuity/resistance with a multi meter. You can clean the terminal in the fuse box with a small piece of fine sandpaper folded over. My convertible top quit working a while back, And I fixed it by pulling the fuse, cleaning the prongs and terminals and reinserting the fuse.

POST 3 / ORIGINAL POSTEROriginal post

Thanks DonQ. I will try your solution and report.. Another point to mention that might be relevant is the jumper wire that is plugged in to the fuse panel right beside fuse A5. Perhaps a previous owner wired in the jumper to provide power to an accessory, such as a radar detector. The fuse itself plugs in and out easily as it should and does not appear to be interfered with by the jumper. Has anyone else experienced this sort of problem? Any and all replies gratefully appreciated.

POST 4Original post

My 03 had the instrument cluster lights out as well. Took the dash apart to "change lights" only to find out there weren't any to change out. The lights are built into the boards. Replaced the master light switch, after reading here and watching a couple of videos. For less than a $100, the new light switch fixed the issue. It also started giving the signal the lights were still on when the car was turned off. I hadn't noticed it had quit doing that. Consider changing the light switch and it may solve the issue for you. Takes about 30 minutes.

POST 5Original post

Cen Cal Mike described a common issue with the Boxster. If you don't want to replace the switch, you can clean it with electronic contact cleaner.
