Dorman - HD Solutions Multi-Function Switch P/N:978-5412
Dorman 978-5409 multi-function switch for the 1993-2007 Peterbilt 320 controls the hazard lights and the latching high beams from the console. It is a direct replacement for the original console switch on this application and comes with its lever.
Hazard lights or high beams that stop responding, or a lever that feels loose, can mean the switch is worn. A blown fuse, a burned-out bulb or a damaged wire or connector can be behind those symptoms too, so track down the cause before you buy. If the switch is at fault, this one replaces it.
This switch fits the 1993-2007 Peterbilt 320, which takes one.
