New to the forum but original owner of my 1979 K5. After reading a few posts I think my headlamp switch needs to be replaced. All my lights work except the two headlamps. They were kind of dim for awhile. I think I was resetting the circuit breaker on the top side of the switch but seems not to work and is crunchy. Any photos or drawings appreciated. Is there an easy way to unplug the wires and remove the headlamp switch and try for an OEM replacement at my local dealer? Thank you
