Ford F Lighting Problem

That does sound like an electrical gremlin. With intermittent lighting issues and a stored error code, I'd suspect either a faulty light switch or a wiring issue. Have you noticed any correlation between the lights acting up and specific actions, like using the turn signal or hitting a bump? Sometimes it's like chasing a ghost in the machine...

Thanks for the quick response. No, I haven't noticed a direct connection to any other function. Where exactly should I be looking for potential wiring problems? Any specific plugs or connections that are known to be problematic on this model?

Given the symptoms, I'd focus on the light switch itself and its immediate connections. It's likely a cable or plug connection of the component defective. Think of it like a loose connection in a household lamp, but with more wires. If you're not comfortable digging deeper, a workshop visit is advisable to prevent further electrical headaches.

OK, I understand. Thanks for pointing me in the right direction! I took it to the workshop. The issue was indeed a defective connection at the light switch. They replaced the connector, and the total repair cost was 95€. Everything seems to be working fine now.
