1999 Chevrolet Suburban lighting problems

On three occasions, consumer took vehicle to dealership due to headlights flickering intermittently while driving. On one occasion they found a bracket that was broken and replaced the driver's side headlamp assembly, but the problem still exist. However, occasionally the dashlights, domelight, and stereo display experience failure which may be the result of a electrical problem.

While stopped at light a motorist informed me that we didn't have any brake lites. After arriving home I had my wife apply the brakes and only the third brake lite came on. I had my wife take our surburban in to the dealer, had it checked out, and was informed that we had a short in the rear lite harness. It was repared for $118. The following day we drove the surburban up to iowa over the memorial day weekend. After returning I was again informed by a motorist that I didn't have any brake lites.
