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.

MY2000 C2 Cab
I rarely drive my car at night - not for any particular reason, it just doesn't come up much. I was driving the other night and I wanted to make the dash lights brighter. Of course I had no idea how because I rarely drive at night. Fumbling around, I hit the PSM switch but the the bulb didn't light. I downloaded a fuse diagram and went out to see if the fuse was blown. PSM uses two 30 amp fuses (E9 and E10). There was a 25 amp fuse in E9 and no fuse in E10. I know that the PSM disable switch used to work as I would turn it off for Auto-X. Replacing the fuse fixed the issue with the light.
Comparing the other fuses with the diagram I found a couple of 40 amp fuses where 30's should be. A couple of fuses were a bit undersized but that doesn't concern me as much as the over-sized ones. The only maintenance or repair that I didn't perform myself was body work. I can't see why anyone would remove the PSM fuse or mess around with the others. I'm the second owner of the car and the the PO was fanatical about having the dealer perform all work.
There were no codes the last time I hooked up a Durametric, but I'll check again.
Scratching my head on this one.
I eventually figured out the dash lights dimmer. The PSM switch was definitely not working with that fuse missing. I tested it with and without the fuse. Not only does the button light come on and off now, but the dash warning for PSM does too. I can't imagine when that fuse went missing or who would have done it. My passenger door wouldn't close after the accident. Maybe the body shop pulled that fuse by mistake when trying to disable the cabin lights?
Even so, the 40 amp fuses puzzle me as there are none listed in the diagram.
