Has this ever happened to you? You turn on your turn signal lever, make your turn and the lever does not come back to the neutral position. Your turn signal just keeps flashing. Just to check it, you try it again and it still doesn’t return. The problem you have – in most instances – is that your Corvette’s turn signal cancelling cam is broken. When the cam breaks, it will not allow the turn signal to cancel and return the lever to the neutral position. If you have a 1963-1967 Corvette, the cure for this problem is just a phone call and about 2 hours of labor away.
Zip Corvette Parts, 8067 Fast Lane, Mechanicsville, VA 23111, 1-800-692-9632, has all of the correct turn signal canceling cams for the 1963-1967 Corvettes in stock. We had this problem in our project 1964 Corvette so just follow this article and we will show you just how easy it is to repair. We’ll also take a quick look at our horn button and button stand as we disassemble our Corvettes steering column.

01: Here is all you will need: A new cancelling cam, marking pen, torque wrench (ft. lbs), 1/2″ extension 6″ Long, 3/4″ 1/2″ Drive Socket, 9/16″ and 1/2″ open end wrench, Phillips screwdriver and a steering wheel puller.
02: Start by disconnecting your Corvette’s battery.
03: Remove the horn button and the horn contact plate. Also, make sure the turn signal lever is in the neutral position.
04: Remove the steering wheel retaining nut. Now mark the steering shaft and place a corresponding mark on the steering wheel. You need to do this so that you can re-align the wheel and steering shaft back into their exact place. If you do not do this, the steering wheel will not be centered when you re-install it.
05: Install the steering wheel puller and remove the steering wheel.
06: Remove the cancelling cam from the back of the steering wheel. For comparison, we are showing you the new cam on the right and the old broken cam.
07: Before you re-assemble the steering wheel and cancelling cam, check the turn signal switch canceling pawl. In some instances the cancelling pawl ends may be broken. If this is the case, you will have to replace the turn signal switch. Zip Corvette Parts also has these in stock. If both pawls are not broken, then proceed with re-assembling the wheel.
08: Install the new cancelling cam onto your Corvette steering wheel.
09: Make sure the turn signal lever is in the neutral (center) position and re-align the steering wheel to the mark you made on the steering shaft. You must make sure they are aligned or your wheel will not be centered. Install the steering wheel retaining nut and torque it to 35-40 ft. lbs. Check your shop manual for torque settings for different years.
10: Re-align the horn contact plate with the horn button stand/contact and re-install. Often, the plastic rivets in the horn button stand/contact will be broken, causing the horn circuit to be continually grounded. Common quick fixes have included sticking cardboard into the stand to open the circuit. If this describes your Corvette’s horn button stand, new reproductions are available from Zip Corvette Parts. (See links at bottom of the page.)
11: Snap on the horn button, re-connect the battery and you are all set to go. If your C2 Corvette’s horn button looks like it’s gone through WWII – chrome peeling, cross flags deteriorated, etc., then Zip Corvette Parts can help you complete your Corvette restoration with a new GM licensed 1963-1967 Corvette horn button.
