Specs At A Glance

Q: Is this a complex installation? A: The switch is located within the steering column housing. Accessing it requires removing the column cover, but the electrical connections are straightforward plug-and-play.

Q: Will this fix turn signals that do not self-cancel? A: If the signal is not self-canceling, the internal mechanical spring mechanism in the switch is likely worn out. This new switch will resolve the non-canceling issue.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
