I've gone through my Haynes Manual a dozen times and maybe it's just me. Aside from the obvious switch in the driver's door that activates the interior lights when I open the door, I cannot seem to find what I presume to be some kind of relay that's part of this circuit.

Before I start swapping out relays trying to figure out why my interior lights only come on half of the time when I open the driver's door, does anyone know for sure if there is a relay involved? If so, is it plugged into the Junction Box or someplace else?

I've looked in several places on the internet for a layout of the Junction Box relays, and I haven't seen anything in any picture that looks like there is a relay there for this circuit. Anyone?

Thanks, in advance.

You might want to inspect the door switch. It sounds more like it has a bad ground (rusty?).

Thanks for the response Yogi... the switch "looks" OK... I'll check it for continuity and maybe swap it with the passenger-side switch and test. It's the "clicking" sound under the dash when the lights turn on that intrigues me. It sounds like a relay, but I have no idea where it's located.

Yogi... you were absolutely right! I missed it the first time. It definitely is the switch... thanks.
