Hi all
on my old 88 chevy the dome light is always on , I checked and disconected the doors switch but they are always on. the passenger door switch has only a wire but the driver switch has two. someone has the schematic diagram for a s10 Blazer 1988 ? may be something goes to ground but the wire looks like in good condition.

thanks

 

That's right, two wires on the drivers door switch and one wire on the passenger door switch

Thanks George
I found the problem , the dimming rotary switch was turned on. I was a little stupid b, I am refurbishing the car and before to install the new ceiling was mandatory to check interior lights.
thanks
