no dash lites/blower motor 89 ramcharger

Kind of hard to read without periods and sentences. The dash lights are controlled by the headlamp switch. It has a rheostat wiper that gets corroded (all cars, even my M-B). Try spraying contact cleaner on the wire coil. If no luck, they are usually cheap. $11 switch for A-bodies. Perhaps same PN for yours. Check rockauto.
