You may look or feel the back side of the steering wheel, looking for 2 screws that hold the airbag to the wheel, these will be internal torq type screws (star) you may have to rotate the steering wheel 90 degrees to access the screws. You should first disable the airbag, by removing the airbag fuse, and or by disconnecting a yellow connector located near the base of the steering column. under the knee bolster.(panel below column). Once the retaining screws are removed, lift bag and disconnect the 2 connector to the airbag, the ground for the horn, and the horn contact wire, which requires you to push down and twist counter clockwise, damage to the horn contact ring will occur if you try and just pull connector from the ring. Now you can remove the steering wheel, may require a puller, and the you will have access to the turn signal switch.

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.

Someone at chevy needs to be slapped over this one. The turn signal flasher switch probably went bad. But this vehicle is different from other vehicles, and from common sense. The hazard and turn signal flasher are not in the fuse box, they are in the middle of the dashboard, just under the radio. You have to take out the screws on the lower dashboard panel, bend it back and finagle the flasher switches out. They are round and plug straight in. The turn signal one is on the driver side. I had the same problem and lost a lot of hair figuring out where they were. Good luck.
