I picked up my vehicle from carmax, and everything was fine. Came home drove to the corner store and no turn signals. Next afternoon, I drove the car and the turn signals were working. Few minutes later my turn signals cease to work again.Took it to carmax two people drove it and no turn signals. Technician gets a hold of it, no problem. His opinion is he can’t diagnose a car that has no problem. So the turn signals work while he had it. Whats wrong with it?
It is probably coincidental, there is a flasher control that can be replaced easily and inexpensively.
If this happens again have the multifunction switch checked if this is a newer model Corvette. GM has problems with the multifunction switch on every model made in the last 20 years. Most of them lose the brake lights when the turn signals stop working. Carmax should pay for this replacement because it’s not easy and it’s not cheap.
