Need help with my van's lights staying on. Hit dash and will turn off. on 2003 GMC Savana 3500

I have already tried replacing the actual light switch. That is not the problem. When I get to a job my head lights will be on even when turned off. I hit the dash near the radio area and they turn off. This happens every time I drive to the next job. Any ideas. It is not the head lamp switch as stated above. Feel like the Fonze from happy days. lol

Sounds like you could have a bad lighting module or body control module if equipped or have an in-dash electrical issue. It sounds like it will require some diagnostic time to find the actual source of the problem.
