Does your turn signal do wierd things? I.E. just turn on a solid light, blink then stop, both flash, don't turn on at all, but your hazards still work just fine. Then here is your problem.

It is the hazard relay located in the center dashboard. It houses the relay for the hazard and the turn signals.
Here's how you fix it, go get the relay; from a dealer (~$45), ecstuning.com (~$29.95).
Yank the old one straight out(it's kind of hard to pull out), but it just pops out, connect the new relay, pop it in and away you go.
Here is what it looks like. As you can see I chewed it up trying to get it out.



Just thought I'd share, cause I had troubles figuring out what the problem was.

P.S. Some one should sticky this.

 

yeah we should start a thread that just lists less known problems (such as this) and their solutions
