My 04 Trailblazer driver side low beam does not work. I replaced the bulb and no change. I checked the socket and found it was bad. I just replaced the socket and no change. The new socket has power at both leads but the bulb will not come on. I had another new bulb on hand so I tried that, no luck. Anyone else run in to this??? I checked the fuses and they are ok too. I am at a loss.
