Sounds like a bad ignition switch.

hey anyone else know what this could be? it happened to me last night coming home and the windshield was frosted as hell and i had a 2in by 2in spot to see through the windshield

I would secound the ignition switch. Being that the dic headlights and blower motor are not in the same system.

Look at OEM Chevy Parts - GMPartsClub.com It looks to be around 92 bucks + shipping.

I had the same problem last fall and everyone said ignition switch. I kept troubleshooting and was convinced that it was the fan switch. I replaced it and the problem went away. How I nailed it down was, once it got to where the problem became constant instead of intermittent, I disconnected the harness from the fan switch and it went away. I turned the switch to off and plugged it back in. The problem was still gone. When I turned the fan switch on, problem came back. Unplugged switch and the problem went away. Lather, rinse, repeat.

ok yeah right now its been just like the light isnt coming on the dic but if i shine like a flashlight on it i can tell its working cause i can see it but its just not lighting up but every once in awhile it will start messing everything up like making my headlights go off and on and shutting my fans off but it used to do it everyday so idk
