Odd electric circuit problem...

[nedinwc]

Sometimes it works, then it doesn't. The interior cab light, windshield wipers, 4x4 switch, glove box light. They all stop. Later they work, then out again. Of course they don't work when I really need them. Not sure, but I think the colder it is the more likely the circuit won't work. I see nothing obvious. Any clues?

since all these switches and lights are related to your dash, then I would think there is a grounding issue with your dash. Might be hard to find. but i'd check and tighten all grounds.
