Mack RD Gauge Panel Light Dimmer Switch Part Number

Recommended Posts

Does anybody have the part number for the panel/gauge light dimmer knob for a 1994 Mack RD? Also, what amperage should the panel light fuse be and what is the fuse number/location. I do not have a wiring diagram for this truck. Thanks in advance.

Finally got around to fixing my dash lights. They are all wired through the dimmer rheostat. If your dash lights stop working it’s most likely your dimmer unit. Very easy fix. Below is a picture of the Mack (Volvo) part number you will need.70F44658-72B1-4819-8A46-B6B5DB172069.thumb.jpeg.c20f888239d77aa6a107a55db51e729e.jpeg21F9F753-F9FE-4839-9173-280AC0BAE93E.thumb.jpeg.f3c953d91e20559adada802ebd724cac.jpeg
