2003 Tahoe LS - When you flip the right turn signal the high beam headlights will come on.
It's not a solid fail - it happens about 1 time out 4.
When you cancel the right signal the high beams go off.
Any ideas on where the fault is ? I have read some about the MFC being a possible culprit.
Other than having a suspicion about what the letters "MFC" stands for I have no clue. LOL
