Lately, my turn signals have been working off and on at complete random. I put a new flasher in and nothing happened. This started happening after I changed my brake booster. Could I have knocked a wire loose or something? Any help is appreciated.
Yeah, they do. It's a a pretty tricky problem to trace down because of the randomness when they work. They just work whenever they want to it seems like.
The turn signal flasher is not mounted on the front of the fuse panel. The flasher on the front of the fuse panel is a separate one for the hazard lights. The turn signal flasher is in one of several places, depending on when your car was made. Some are behind the fuse panel on the back side, others are behind the radio and some are behind the glove box.
Other possible problem sources for the turn signal malfunction are the ignition switch, multifunction switch and the plastic shell that holds the turn signal wiring connector pins.
A word of caution about multifunction switches is in order here. The multifunction switch (high/low beam, wiper, turn signals) are different for different years. 87-98 will work in any 87-89 car. The 90-93 switches only work in 90-93 cars. You can't put an early model switch in a late model car, nor can you put a late model switch in an early car.
