GET A GOOD FUSE TESTER TURN ON IGNITION SWITCH. TEST EVERY FUSE. 2 FUSEBOXES ONE UNDER THE HOOD, ONE INSIDE THE CAR. FUSES CAN BE TESTED WHILE IN THE BOX. FUSES HAVE TEST POINTS FACING OUT. POWER ON ONE SIDE, BAD FUSE, POWER ON BOTH SIDES, GOOD FUSE POWER ON NEITHER SIDE, SPARE FUSE.

Sometimes the fuses will look OK, but still be bad. Did you check the fuses with a test light?

Oh you'll love this I just fixed that problem. Yes there is a flasher fuse there are actually three. One in the fuse box and two under the dash panel. Drop your plastic panel at the bottom and look for two half a dollar sized round fuses those are your flasher fuses. They run around two bucks at your nearest auto part I would replace both so you want have that problem again but yes there is a flasher fuse for it. Good luck

Well just guessing here that you think it's a fuse, or fuse's because you're looking for the fuse panel.
I can almost certainly say it's not the fuses, as each of the problems you've described are run off separate fuses. Unless this car was just bought, The fuses may of been removed. If this is the case, I BELIEVE the fuse panel in this car is located on the left hand side, between the door and the dash.
