Turn signal flasher?

It sounds like you have a signal flasher that is out which is integrated into the hazard switch. Here is the location so you can test it out and fix the problem. If that doesn't do it there is a lighting module that I would replace.

Here are some guides and diagram (below) that will help you see what the problem is.
