Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

I'm not sure what I did wrong here, but I did the 'poor man' OBC mod as described in the 101 projects, I used the proper wire connectors for the cluster plug, and inserted them in the proper positions, and after doing that, all of my cluster lights stay on, although slightly dimmer than normal.

If I take off the parking brake I can see the light gets a bit dimmer, but still stays on, same for the ABS, brake pads, check engine, battery, wing, etc.

My next test is to try removing the new pinned wires from the cluster harness and see if that changes anything, but if anyone has any ideas, I'm all ears.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

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

When I had the cluster out I tried to swap in LED bulbs, but they didn't work at all so I swapped in all new bulbs, and still no change.

POST 1 / ORIGINAL POSTEROriginal post

Hello all, I'm not sure what I did wrong here, but I did the 'poor man' OBC mod as described in the 101 projects, I used the proper wire connectors for the cluster plug, and inserted them in the proper positions, and after doing that, all of my cluster lights stay on, although slightly dimmer than normal. If I take off the parking brake I can see the light gets a bit dimmer, but still stays on, same for the ABS, brake pads, check engine, battery, wing, etc. I have even tried unplugging the switches, and it still does it. It seems like there is something grounded that shouldn't be, but I can't seem to trace it down. When I had the cluster out I tried to swap in LED bulbs, but they didn't work at all so I swapped in all new bulbs, and still no change. I know for sure that prior to doing the mod there were no lights on and they were working properly, so it's obviously something I've done, I just can't figure out what. My next test is to try removing the new pinned wires from the cluster harness and see if that changes anything, but if anyone has any ideas, I'm all ears.

POST 2 / ORIGINAL POSTEROriginal post

Well, I did a lot of driving on the weekend, and just before I got home I hit a decent size bump in the road (they are doing sewer line work in our town so all of the roads have cutouts across them, so filled better than others) and now the lights are working properly...which is both good and bad. Good that they are working, bad that I don't know what the issue was, and why hitting a bump fixed it.

POST 3Original post

My guess is you had either a short that is now unshorted or a loose connector that finally seated. If the dash lights are all functioning properly now, I would leave it alone and see what happens. If it's the former, it will cause more trouble. If it's the latter, it may not. Sent from my SM-N975U using Tapatalk

Agreed. Not sure where the issue was as I have played with the cables a bunch and nothing made a difference. At this point I'm leaving it alone, if it happens again I'll have to tear into it more deply.
