My husband and I were on our way home last year, when he jokingly smacked the turn signal a little too hard. Now, it constantly flashes and blinks and won’t turn off. My husband had to pull the fuse out of our fuse box, so that the turn signals were currently off. This is also made it to where we have no heat and no air conditioning as well. I was wondering how we would fix the problem of the turn signal constantly being on?

Hi,

If he hit it hard, it sounds like the switch has failed internally. I would recommend replacing the switch.

If you look below, I attached the directions for replacing the turn signal switch specific to this vehicle.

Take a look through the directions and let me know if you have questions. Also, let me know if this resolves the issue.

Take care,

Joe
