Why do the wind shield wipers come on when I start my 2010 ford mustang?

The windshield wipers on your 2010 Ford Mustang may activate when you start the vehicle due to a malfunction or a stuck wiper switch. It could also be a result of the wiper control system resetting when the ignition is turned on. If the wipers continue to operate without manual activation, it's advisable to check the wiper switch or consult a mechanic to diagnose any electrical issues.
