When I open the drivers door the drivers dash light doesn't come on, only the passenger dash light, the rear courtesy lights and puddle lights come on, when I open the passenger door all the dash including the drivers side work. Any reason?

As I recall the driver's side light is isolated so that it won't blind the driver if the dashboard "interior light" switch is used while driving

Yes, there is a diode shown in the circuit diagram that would cause this.

This should happen only when the ignition is on, as a protection against the driver being dazzled (as if!). Ignition off, both should come on.

 

Thanks guys. Just checked with ignition on and off and it's oporating as it should,
I've owned this 29 years and never knew that. 🎓🎓
