LS1 Strange Instrument Cluster Issues Well I just ran into another problem with my F body Trans Am I had been driving the bird about a week ago today. I was driving around 8:00 pm when suddenly my instrument cluster light turn off while driving. I analyzed it a bit further and notice that all my tachs , speedo, odo, temp, where all working as they should. My tach had remain on and was still calculating the mileage. I thought the light has justg blown out and cause it to turn off.
The Next day at my gf house we were going to go fishing so I walked up to it as normal turned it on the first crank I then noticed none of my tachs work not a single one and the instrument cluster light still didnt work. I took it to a local mechanic he found that 3 fusses had blown one on the dash and 2 inside the engine bay. He replaced all 3 then my tach and everything else starting working fine as it should. I took it to the lake and shut her off.
A few hours later I went back to the car turned her on cranked right up and
then now only the oil pressure and the alternator are working nothing else is not even the hatch release I checked the fuses they all seem to be fine. Anybody know where I should start?

Anyone Im still chasing this I been trying to search the forums but no one with my particular problem and I cant seem to find the switch either. I work for NApa anyh other names it might be called?? my Fog light, Running lights, and dash light dont come on
I have had the same problem & haven't found a solution yet, ...
The Dimmer/Headlight switch combo unit can be found on Ebay.
Mine started when my dimmer switch overheated & burnt up, ...
Put a new one in it & now the backlighting for the gauge cluster does not come on.
But the dimmer switch somewhat works because the lights on the steering wheel will change with movement of the dimmer.

i don't mean to be a smartass, but have you adjusted the dial on that switch? it could be turned all the way down, causing the lights to be dimmed completely. Try turning it up to see if it changes, and then when you keep turning, it should activate the interior lights.... Does that all work?
