I have a 1986 C 20 and it is a two wheel drive truck. What is the 4wd light on the dash indicating when it comes on?

Sounds like a previous owner installed a gauge cluster from a 4wd truck.

Funny they left the bulb in. Funnier yet it is illuminating in a 2wd truck.
Time for a little wire tracing to find the answer

That’s the way it came from the factory. My grandfather bought this truck brand new in 86. When it was given to me five years ago and 69,000 original miles.

Another example of many parts used in many applications. It doesn't surprise me that dash bezels fell into that reality.
Trick now is to find where the ground is being made and eliminate that. Or pull the bulb and save for later.

Just noticed, welcome!

Gauge cluster was original with the truck in 1986. My grandfather bought the truck new and had the truck his whole life.
