How to Replace a Mustang Turn Signal Switch
The Mustang is a sporty car that has been manufactured by the Ford Motor company since 1964. The Mustang is available in several different guises, ranging from an economical grocery getter to all-out race machine with a powerful V-8 engine. The turn signal lever in your Mustang actuates the turn signal switch, which is mounted in the steering column beneath the steering wheel. The switch in even a well-maintained Mustang will eventually wear out and need to be replaced.
