2003 Chevy Monte Carlo

I can't help you with the problem, other than to say we have a similiar problem on our 2004 monte carlo.

After about 2 months, lights went back to dim. I can't remember if we hit the bright/dim selector handle on the steering column.

Now we just leave the dims on and refuse to hit the selector handle, until we get it fixed. In our case there used to be a click, when you pulled the handle, but now the handle doesn't click when you pull it.

If we find the problem, I'll let you know. Please do the same for us.
