My 1992 plymouth voyageur has got no instrument panel lights. Also my check gages light came on for the first time. I tried changing the fuses but to no avail. Also when the lights went out so did the lights in my radio and heater controls, but the lcd still works in the radio I think. This just happened last night.

Welcome to the forum but you should try posting in the Plymouth or minivan section for other common owners. Sounds like the dimmer switch which controls all those.
