On 95-97 and 1998, both the turn signal and hazard flashers are located behind the lower dashboard trim just to the left of the cigarette lighter. You can not get to it without taking apart the trim (stupid design). Or you have to drill a 2" diameter hole in the trim with a velcro cover so you would never have to do it again1999 and later it is under the glove compartment
to disassemble it without drilling
It's behind the panel to the left of the cigarrette lighter. You need a Torx 25 screwdriver and another screwdriver for those hex shaped screws, forgot the size. First unscrew the 2 Torx 25 screws beneath the steering wheel. Then unscrew the rest of those Hex screws on the bottom. The panels overlap, so be prepared for a lot of unscrewing. You do need to unscrew the middle black panel on the bottom, right beneath the cig lighter. It's held by two Hex shaped screws, one on each side and are hard to unscrew. Also you need to remove your spare change sliding tray to unscrew the last hex looking screw. Once you pop your panel off, the turn signal flasher is the right one. The Hazard flasher is the left one. You can find a replacement part at Autozone, and DON'T get the $184 Flasher switch, all you need is the signal flasher. It's shaped like a cylinder with TWO prongs on it.
