I have this 1989 F-250 where the dome, map, and glove box lights don't work. The cargo light does work. No fuses blown that I can see.

Can somebody provide the electrical drawings so I can know where to start on this?

Thanks

 

"That I can see". Does that mean you actually took each fuse out and tested it, or only looked at them?

 

OK here are my results so far.

1. Dome light simply burned out. Oddball bulb, need to replace.

2. Map lights do not come on except when headlights are on. This schematic I found does not agree with that but the wire color to the map lights in the headliner is black so that makes a little sense.

Glove box and hood lamp yet to be explored.

I'd like to change the map lights over to hot at all times. Anybody have a schematic for how my 89 is actually built if they changed it from the 88?

Thanks
