I use my 99 trans am almost every day, the previous night I had gone for a ride and everything perfect as normal. The next day I went to start the car and it fired right up as normal, then a few seconds later I heard a click and my gauge cluster problem started. The tack went dead, fuel gauge went dead, and temperature gauge is dead. There are numerous warning lights also reading- abs inop, service engine lights on, airbag lights on. All happened at once right after the "click". The car continues to run and act normal, as far as I can tell it is just the gauges. I can hear the fan kick on when idling. Could there be an inline fuse somewhere or?? It is just weird that it happened all at once.

Has anyone heard of this happening before?
There is a new alternator and volts are good.
I checked all the fuses in both boxes, they are fine

Can you get it over to someone with a scan gauge? Im wondering if you are throwing any codes.

Seems to be a lot of cluster issues lately.

I just went to Auto zone and Advanced auto, both scanners couldn't scan, they came up as an error. Before this happened it was working.

could they all be interlinked maybe with a bad dash?
I'm still hoping someone will say there is a fuse hidden somewhere that's blown
I was searching around and other people were having issues with the bcm, but my windows and radio are working properly, I took bcm out just to do a visual chuck and there are no cracks or corrosion that I could see
Stumped and frustrated

It's a long shot and might not even apply to all of your issues but every time I have had an effed up gauge it's been due to a bad alternator.

Sounds like a popped fuse. Did you check the fuse in the instrument panel on the drivers side for the gauges? I think it is fuse #9 IIRC.

yep sounds like a fuse. check fuse's first wen it happen to me it was a fuse and that popping noice sounds like a fuse as well wen they go out sometimes they pop

Triple checked fuses, all the fuses in drivers side and the two boxes of fuses under the hood are all good and alternator was replaced about two months ago also reading around 14.6 when running. would there be any hidden fuses, say other that in them locations? It still sounds like one feeder wire that must of went. I guess my next step is to take dash apart and start process of elimination. I have some spare gauges laying around. I appreciate everyones imput.

check you ground connections and breaks in wires.

ground G200&G201 are at each side of car
near door, probably behind kick panels.

also disconnect the batter for 10mins.

took off grounds behind both kick panels and reinstalled, they are good. next I took cluster off to inspect, and no visual problems. there is power to all gauges, just not getting a reading from the ones listed because when the key is off they are below 0 then with key on they jump to 0.
so I went to under the hood and started with temp sensor, unplugged it and with the dummy light, there is no power there. thats were I left off and will be tracing the feed wire

finally found the problem. The wire on the top of the alternator was replaced by a previous owner and it ended up corroding through and splitting near the solder connection.
