Headlight Switch problem

[JJ052653]

I have had to replace the Headlight switch 3 times including the plastic connector that attached to the Head light switch. Eveytime I replace switch I find the Plastic connector is melted and causing the Dashboard lights and rear tail lights not to function.

Either the headlight switch is defective (3 of them, I don't think so) or
there is some other problem.

Can anyone give me a suggestion what is causing the problem, what
to look for and how to correct it

thanks Jim

I've replaced mine 2Xs. Must be some kinda high current going into it. Now I keep the Twilight Sentinel off and manually turn on and off the headlights. No problems since.

Thanks for the input. I don't have the Twilight Sentinel option. What I believed happen, is the dashboard dimmer over a period of time, fails
and cooks the switch, connector, wires and the tiy delphia connectors(which are a pain to get). I had to re-splice the corrupted connectors.

I agree, too amps going through the wires. Great GM design.

Did you know that there was a NHTSB recall on cars with Twilight Sentinel ?
