Symptom: Dome light always on, door ajar light on. You have checked both front door switches and they are working fine.
I have confirmed this in the wiring diagrams of 1998 through 2000 rangers, many more may be affected.
For some reason on the 4 door models (the extended cab where the little rear doors open backwards) Ford felt it would be a good idea to put door switches on the back doors also.
One wire is ground, one goes to the gem but not exactly. On both doors the non ground wire ties in with the right front door switch! You can unplug the wire from the front switch and do a continuity test between the colored wire (not the black wire) and ground and get a beep or a light.... one of the rear switches is bad.
The rear door switches are wired in parallel if either of them are smoked then you will get continuity. These switches are "normally open" design so they actually close when the door is open. The ground is just a signal to the GEM to do its thing and turn the dome light on or trigger the door ajar light and the battery saver thing that eventually turns it off if it seems you have forgotten to.
I haven't found out where the wire is spliced in yet to the right door wire but I will unless someone already knows. I'm not going to attempt to fix the rear switches I'll just clip the wires because... (here's the logic question)...
WHY WOULD YOU HAVE A DOOR OPEN SWITCH ON A DOOR THAT CAN ONLY OPEN IF THE MAIN DOOR IS OPEN?
Maybe it's just me?
