Left side instrument lights not working

[themechanic]

1969 Dodge Coronet R/T with standard dash/gauges.

All wiring harnesses are new, all dash switches are new or rebuilt, all dash lights are new LED, all bulb sockets are new. Also, cluster was taken out and restored. Right side instrument lights, radio and aftermarket gauge lights light up and dimmer controls them.

The round plug at back of cluster was un-taped and each terminal slid out, reshaped (round) and replaced then re-taped plug

Switched one light socket that is working with one on the left. The result was no lights on the right and one working on the left.

The circuit board appeared to be good. So, I just cleaned all the contact surfaces and re-installed.

Also added an extra ground wire to the ground the cluster to the dash frame.

Stumped. Any other ideas are welcome, FBBO.

New circuit board with new led lamps so you got a new voltage limiter too? electronic version? are all the circuit traces in tact? no breaks? Power feed to instrument lights goes through headlamp switch and dimmer switch trace it all the way from the fuse box to the cluster, wrong connection between will knock out lamps.

loose pin to circuit board is a common problem. I had to solder all of mine back together

Yes, I got a new electronic voltage limiter.

All pins on the board are tight. Does not change with wiggling the plug.
