Hello...from what you are describing, it sounds like the contacts in the switch are worn out. The fact that you can make the circuit, and then lights the lights do work, by simply manipulating the switch means the rest of the circuit is OK. An Auto Electric Specialist from YourMechanic could replace the switch on your truck during a mobile visit if you desire. Simply contact us for details and to schedule.
