I was driving at night and both headlights (low beams) started flashing off and on then went completely out, I hit the dimmer switch and turned the hi beams on and they worked fine. When I shut my high beams off my low beams came back on and stayed on for the rest of my 120 mile trip. Four days later on my way to work in the dark the same thing happened, the following day my low beams would not turn on and I have to hold the dimmer switch to keep my high beams on or I will have no headlights. ( one hand on the dimmer switch one hand on the steering wheel). I suspect it is the multi function switch in the steering column which is a $300 part. But have not had it professionally diagnosed. This is a real safety issue that gm needs to address!.
Pertaining to my 2005 Monte Carlo lt 3. 8 v-6. . . While driving with high beams on the headlights will shut off. . . This has happened at least a dozen times since I bought the car used with 23,000 miles on it last August 2009. . . When they shout off I have to use the dash switch to turn them back on. . . I did end up driving off the edge of the road one evening when this happened. . . No major damage done to myself, the vehicle or property where the incident occur but scared me really bad!!! I did go back and rack the ruts out of the edge of the lawn where it happened. . . Very dangerous situation. . . Should be and needs to be addressed by gm. . .
