Hello all,

Trying to figure out what the issue is with my instrument cluster.

I own a 91 560SEC w126 and having issues with my cluster in regards to the illuminating lights. All of my lights work except for the 2x that illuminate the tac and mph. All of the bottom lights works, I've tried 3 different clusters all which do the same thing. Not sure where to start looking if anyone could give me some advice I would highly appreciate it.

Thanks
