1989 Jaguar XJS Gauge Cluster Lights

My gauge cluster lights won’t turn on at all. What couple be possible solutions so I know what to look at.

Might as well start by checking the brightness adjuster above the driver’s right knee. Make sure it works, is connected right, etc.

Ah, make that left knee for US?

No, mine is above right knee on my 1988 US LHD car.

Mine was corroded. Also, when removing the panel to access, those three wires easily become disconnected.

I would first check fuse.
