Mine's been like that for about four years now. :rofl:

I think it's a corroded contact/connector in the driver's side door switch. However, I haven't really dug into it yet because when I do, I'll be pulling up some pretty rusty parts of the cab, and I don't want a gaping hole in the bottom of the B-pillar right now.

Have a look at this, too:

Make sure the map bulbs arent blown first :) I'm betn on the switche being faulty like Sig suggested^^^ I bet if you start to mess around with that switch you can get the light to come on.

I have the same problem as typaolino92. Dome light won't turn on when I open drivers side door. Based on the diagram, Sig, will I be able to access the switch to see if it's corroded by removing the B pillar interior trim? I looked through Hayne's today and didn't find much to help me out.

I think so, yeah. I haven't pried mine apart yet.

Did I also mention I'm blind as a bat? I stared at that switch all day and never noticed that it was being held on by a single Phillips screw. :doh0715: I took it out, and as I was prying the switch off of the connector, the dome light came on for a split second and then went back off. I took it out and look at the connections on both ends, and there doesn't seem to be any corrosion. I plugged them back in and out a few times, but I was never able to make the dome light come on again.

If Ford would have been nice enough to install the same switch on both doors, I would have taken out the passenger switch and tried it on the drivers side, but the passenger side switch is the one built in to the front of the door. Great.

Is it safe to say that this may just be a faulty switch? Could the connections be corroded even though they don't appear to be? And if so, what is the best way to clean them? They are all recessed into the plastic and difficult to access.

Those switches can and do go bad. Sometimes I have to twist mine a bit to get the lights to come on, its in need of replacement too.

the MFS testing is done with connectors disconnected

Problem solved. I went to the local Pull-a-Part and stole a few from some Aerostars. I came home, hooked one up, and voila, we have dome light.
