Main problem: The gauge cluster does not illuminate when I turn on the headlights.
Additional problems/observations: The gear selection indicator (P, R, D, etc...) lights, on the cluster, work as long as the head lights are not turned on. Once I turn on the headlights ALL illumination from the cluster disappears.
I jumped the Black and Red cables on the dimmer connector but ONLY the gear selection indicator light, on the cluster, illumated and very faint.
Should I replace the dimmer switch or does this seem like a different issue?
