my turn signals operate..my lights..turn signal indicators..dash light

Resolved Question:

With the lights off my turn signals operate fine, except when I press the brake then they blink fast. When my lights are on, the turn signals blink fast and when I press the brake, they signal extremely slow. When the lights are on and I hit the brake, the turn signal indicators on the dash light up. None of the bulbs are out. What is the problem?

Welcome. There are two possible causes. First if this does it signaling only one way, then I would suspect a ground issue in the back. IF this is both ways, then the signal flasher unit on the back side of the left dash fuse block is the issue.
