I need some help. I have a 2005 Monte Carlo. Recently, the passenger headlight stopped working, both high and low beam. The orange running light works fine, and the driver side headlight has no problems, the low, high beam and running light all work on that side. I verified it was not the bulbs on the passenger side, so i bought new bulb sockets and replaced the old ones. The lights still won't come on. I am at a bit of a loss now. Suggestions?
