Awhile back I was having problems with tail light and instrument panel light fuses blowing. I replaced the light switch and instrument panel and dome light switch.
when I turn on the lights not important if just parking or all of them and adjust my dimmer switch for the instrument panel the lights in the dash do not come on and it will kill the heater lights in the dash. It also makes the dimmer switch get hot and the heater blower and plights seem to dim out when trying to turn on the light in the dash. Due I have a faulty circuit panel behind my dash?

Sorry for the late reply. If it is blowing fuses, check the wiring diagram for everything on that fuse circuit. Check the circuits one at a time, check voltage and ground.

If the dimmer switch is getting hot to the touch, maybe faulty dimmer switch or the wiring in the steering column. Even with multiple issues, by fixing one circuit may fix some of the others.
