Headlight Switch problems of the 2004 Buick Lesabre

When switching headlights from high to low and low to high beam occasionally the lights go dark. This is a scary situation at high speeds. Luckily the lights usually come back on if the leaver is depressed several times. I have been told that the only fix is a new switch assembly at over $500 just for the switch not to mention the labor cost. I understand that the '07 Buick la crosse had a recall on this switch. I suspect that my '04 la sabre may have a similar switch. There are a two other functions on this switch, l/r signal, windshield wipers/washers, all of which work without a problem. I got no satisfaction from my gm dealer when I requested help with the repair cost.

The contact owns a 2004 Buick Lesabre. The contact was driving 65 mph when the exterior headlights failed. The contact stated that the failure would occur intermittently. The vehicle was inspected by an independent mechanic and the contact was advised that she would need to replace the directional switch. The vehicle was repaired yet the failure recurred within 7,000 miles. The dealer was contacted and offered no assistance. The vehicle was not further repaired. The failure mileage was approximately 100,400. Updated 5/2/11 updated 05/13/11.
