Can anyone help me with how the rear interior light in my 1994 crew cab van works? There's a momentary switch to the left of the steering wheel that lights the ceiling light in the back of the van but I can't work out how to make it stay on, but it sometimes stays on all on its own.
I don't use the light much but when I do it seems to do whatever it wants - if I've been faffing with it it sometimes comes on with the front interior light when I turn the ignition off and open a door, and yesterday evening a neighbour told me it was on when it was all locked up! I went out and pressed the button and it's stayed off since because I've left it alone.
It would be good to know how it actually works because it's been converted to a day van and a working ceiling light would be useful now it's dark in the evenings.
