Assuming the signal lights still work, no. But a bad brake light switch or a blown brake light fuse could.
Probably the flasher unit needs to be replaced. This is an electronic switch which usually mounts underneath the dashboard.
Look for either a blown fuse or replace flasher unit for the signal lights (it is separate from the hazard lights flasher unit).
A bad turn signal flasher typically won't prevent the brake lights from working, as they operate on separate circuits. The flasher is specifically responsible for the turn signals, while the brake lights have their own switch and wiring. However, if there's a more extensive electrical issue or a shared ground problem, it could potentially affect both systems. It's best to troubleshoot each component individually to identify the exact cause of any malfunction.
turn signal switch needs replaced!
On the 1979 B200 Sportsman V8 if the brake pedal makes all signal lights come on and hazards and flashers do not work on their own, it could be the flasher, but the culprit could also be a burned out bulb or a short in the wiring.
It could be the turn signal switch in the steering column.
The 1995 Mitsubishi flasher relay switch and the brake light relay switch can be found beneath the dashboard. Both switches will be on the drivers side of the dashboard, near the brake pedal.
The turn signal switch overrides the brake light circuit while the turn signals are on. If the switch is damaged or worn out the brake lights won't work.
A short would blow a fuse. I would check the flasher which is under the eash on the drivers side. The emergency flasher is different from the turn signal flasher.
Replace the signal flasher relay.
either dimmer switch or blown fuse If you are saying that the tail brake lights are working but the third brake light is not....It may be a defective turn signal switch in the steering column.
It needs checked out but both the hazard and brake lights go through the turn signal switch.
