When My tail lights are on my right brake light won't work and my left brake light dimms. I already replaced the brake lamp switch and the bulbs. My next try would be the turn signal switch. What else can it be?
It might be a ground wire loose I would check all your grounds for carosion and see if any are bad
First thank you for the answer. My brake lights work fine until my head lights and tail lights are on. Would a bad ground still have that effect?
