1995 Buick Regal Q&A
1995 Buick Regal Question: My brake lights dont work unless my high beams are on.
My brake lights dont work unless my high beams are on and i have checked into this issue and noticed that it could be a few things i heard that ut is possible to be a turn signal switch but i dont want to replace that if its not whats wrong any ideas on how i could check this or what else i could do to fix this problem? - michaelwunder99
The brake lights do feed through the turn signal switch, but the headlights are a different circuit. The only possible common would be the dimmer switch. I don't remember if it's a combination switch, if so I would consider the switch, but I would do some circuit test to verify. - ProfessorG
