My 1989 chevy K2500 dimmer switch only works as on or off, does not dim. I first thought that I did this when adding LED dash lights, but I notice the heater control does not dim either. Does anyone have any advice to troubleshoot this issue? Is there a way to test the dimmer switch? I don't think it is the dimmer switch because I have two that do the same thing, but it is worth checking this out if there is a way to test the switch.
