Lights wouldn't work. took it to local gm dealer, told it was the dimmer switch and it is a common problem with these cars and fixed it under recall.

I've been having work done on this car for about a year now and everytime it get back to me there is another problem. This time it just happens to be the headlights. I would really appreciate it if I could figure this out without having to give up an arm and a leg to fix it.
