This has been bothering me for a while. I took out my gauge cluster, replaced the turning signal bulbs because they were not working plus all other just for fun. All other gauge lights work. My signals do function. Is there bad ground somewhere? My cluster looks good from the back, no burn marks or otherwise. The stamped circuit, if that's what it is called, looks fine. One indicator worked over the summer for a few weeks. Any help would be appreciated. Thanks

Your printed circuit board is grounded at three parts. There are two small screws or bolts that fasten the circuit board to the gauge housing at both turn signal leads. The third ground screw is at the top (This one grounds the lights). Follow each lead on the board to make sure it is grounded to the gauge housing.
What were the conditions of the sockets, are the leads on the socket making a good contact with the board?

The sockets seemed to be ok. Maybe I should clean them out. I will recheck my grounds at those posts too. Thanks!
