Turn signals date back almost as far as the automobile itself. In the early years of automobiles, drivers used hand signals to indicate they were about to make a turn. Different system came and went, some lasting longer than others. It wasn't until 1939, when Buick introduced their own “Flash-way directional signal,” that Americans could get factory-installed, electric turn signals. The flasher unit for the 1997 Chevy S-10 is hidden behind the center of the dash. You can access it, but you have to remove the knee bolsters from both sides of the dash first.
Items you will need
- T-25 Torx driver
- Nut driver set
Put the transmission in reverse, if your truck has a manual transmission. Look under the dash and find all of the bolts and screws that hold the driver-side knee bolster to the bottom of the dash. There are four screws toward the top of the panel and eight screws across the bottom of the panel. Remove the hex-head screws with a nut driver, and the Torx-bit screws with a T-25 Torx driver.
Remove the screws for the knee bolster on the passenger side in the same fashion. Pull out the ashtray, push down on the retaining tab and pull it all the way out. Remove the hex-head screw. Pull out and down on passenger-side knee bolster to remove it, then remove the driver-side bolster.
Find the turn signal flasher. It is silver in color and has the shape of a cylinder. You'll see two side-by-side. The left flasher is for the hazard lights and the right one is for the turn signals. Grasp the turn signal flasher and pull it out of the power distribution center. Plug a new flasher unit into the power distribution center.
Lift the driver-side knee bolster into place and tap around the front edge to engage the retainers. Install the screws. Tighten them just snug. Install the passenger-side knee bolster and tighten its screws snug. Push down on the tab and slide the ashtray into its cavity in the dash.
