Thread: Only Half of Gauge Cluster Lighting Up But Bulbs Are Good??? 03 GTP

I pulled the cluster on my 03 GTP today to replace what I thought would be a couple blown bulbs on left side of the cluster but… When I put the new ones in they wouldn’t work… I then swapped them with the right side working bulbs and still a no go??? What could it be?

Come on guys! 50 views, someone must have an idea???

Im having the same problem, glad to see im not the only one. SOMEONE PLEASE ANSWER THIS!!!!

No I'm not sure if there's power there or not. I was kind of in a rush last night and didn't have time to dig out my light tester.

Will Do, thanks! Any tip or pointers on removing the circuit board?

once you pull the cluster.. there should be tabes holding it together.. perhaps some screws.. take it slowly and it will easliy come apart once cluster is out.

And...while you are at it.. follow the circuit to look for any breaks in the loop.

Will do guys! Thanks for the help! I'll let you know how I make out.

The circuit board? Its not like the DIC where its a hard plactic piece with soldering points. The instrument cluster is a flexible piece with foil tracers and no soldering points.

i've personaly never pulled out a GP board, but I have pulled out many clusters due to something not working and most had an issue with soldering points.. If there is no points, look for breaks.
