problem #2

Jan 232013

Trailblazer LS 4.2L

  • Automatic transmission
  • 175,000 miles

The voltage drops spontaneously and lights dim. this causes problems with other drivers too because they think I am flashing my lights at them. this happens often and can't find a solution because it wont do it for the mechanic.
