My signals are going crazy. I'm out of ideas, so I really hope you guys can help.
Here's my list of symptoms:
When I put on my left turn signal both of the rear lights blink, so it looks like my flashers are on.
When I hit my breaks, both rear turn signals light up (solid, not blinking)
Right signal works alright unless I hit my breaks at the same time.

So far I've replaced both the turn signal flasher and the switch itself. I don't even know what else there is to replace.

 

You should check all the connectors and the wiring in the rear area. It sounds like you have some kind of a short.

 

Also check the grounds. If it's easier for the current to flow through the other bulb than to ground, that's what it will do.

 

Replace the turn signal bulbs in both FRONT and REAR. One of the sockets is probably corroded and allowing power BACK into the system. Had the same problem on my '92. The quarter panel wheel wells rusted thru behind the wheels allowing water and crap to blow right into the sockets and turned them into rusty hunks of crap.

Unfortunately the sockets are as hard to find as unicorn farts. Only bet is a junkyard. Once fixed, you will need to stop the water from hitting them.


Remove one side bulbs at a time and hit the blinkers. See if the other side stops blinking also.
