When at night, it's important to have functioning lights to be able to gain visibility among the sea of lights.

Have no fear because we are here to help you repair the turn signal cam on your 1993 Chevrolet.
Difficulty level: Hard
- Steering wheel puller
- Small thin screwdriver
- Small pry bar
- Turn signal cam replacement
Step 1: Take out the horn cap and disconnect the horn wire from the cap. Briefly, twist the horn wire counterclockwise to be able to remove the cancel cam in column.
Step 2: Take out the lock washer from the steering wheel input shaft. Remove the input shaft nut (7⁄8 inches or 21mm).
Step 3: Using the steering wheel puller, remove the wheel. If you don't have a puller, then just tug on it for awhile until the wheel will come off.
Step 4: Use a small thin screwdriver to take unscrew the locking tab cover. Pry it up around the detents that are like in the 3'oclock and 8'oclock positions.
Step 5: Look for the retaining clip at the base that has to be removed to be able to access everything. Use the small thin screwdriver to remove the clip, the locking plate, and the cancel cam.
Step 6: You will find two screws for the turn signal cam, one for the turn signal cam switch and the other for the turn signal stalk. There are three plastic tabs that join the turn signal cam to the turn signal switch. Put them back a little and pull the cam from the switch.
Step 7: Mount the new cam. Put the springs in the exact same place on the front side and flip it over to do the same with the contacts of the hazard lights.
Step 8: Pull out the signal switch of this set-up since the retaining nut from the turn signal stalk may have fallen into the upper column. Push the retaining nut through both the switch and cam as you put the units back together.
Step 9: Carefully place it back into position, making sure that the three plastic tabs are back in the same place. Put the screws back, install the contacts on the front, and mount the turn signal brace.
Step 10: Turn the key to check if the turn signal lights up.
Step 11: Using a small pry bar, push the retaining clip back into place on one side and then in a circular motion, push it into place all over.
Step 12: Put it all back and voila! You're job is done.
