reher555 is right. these are all through the turn signal switch on the column, with the exception of the hazards. They are on a different flasher. I would check all grounds and change the bulbs. If it still does it, dive into the steering column. Be careful with that air bag in there, pull the fuse and lett it sit for atleast 20 minutes to drain the residual power left in the AIR BAG system before working on it!
