I just bought a 2001 TA ws6, my right high beam doesn't work, I replaced the headlight and it still didn't work, the ground is good, now this morning I was cleaning the bugs off my headlights and I have no low beam on the same side, it worked fine last night, anybody have a wiring diagram on the headlights. The car is going into the pontiac dealer tommorrow to check the converters on the exhaust, it's throwing the 0430 code on bank 2. I might just have them check the headlights on the right front.
