Steering Wheel
for your 2020 GMC Savana 3500
Your automobile's horn is an important tool that's easy to take for granted — until it stops working. Steering wheel horn systems help you prevent accidents by alerting nearby drivers who aren't paying attention. They also save time by letting you pick up your kids from school without leaving your GMC Savana 3500. Repairing a faulty horn isn't difficult with the right steering wheel parts.
Horns work differently depending on the age of your GMC Savana 3500, but the basic principle is similar. The steering wheel has a horn button connected to a special relay circuit. Pushing this button closes the circuit and sends current to the horn relay, which directs electricity from the battery to the horn. Horn problems are usually caused by the steering wheel button or a burnt-out horn relay.
