Passenger side door jamb switch
So, I've got this little courtesy light switch thingy bothering me.
The passenger side door light switch is not seeing 12 VDC. All of the other switches are reading something close to 12 volts. After looking over a schematic, provided by The Captain, I'm having trouble actually locating where the orange wire for this switch connects to. It looks like, again according to the schematic, the orange wire branches off into two directions. The first is to a body control module and the other is the anti-theft system.
The BCM is directly behind the glove box, right?

So, I block behind the glove box is the BCM I am looking for on the vehicle. Now, does anyone know what I can do to get this door jamb light switch to work? I'd even consider by passing it just so the courtesy lights go on whenever I open the other door or tailgate.
Ideas?
Please?
LOL
Update:
So, I just finished checking the wiring from the passenger side door switch. With the voltmeter, I connected the black wire to the black grounding wire for the switch and the red wire from the meter to the orange wire for the switch. After doing this I got a reading of 1.5 VDC. I uplugged the TBC from under the hood fuse box and the lights went out. So, there is something wrong with the wiring in the BCM, right?
Ideas?

Well, I'm trying to figure this one out.
To date, I have replaced all three switches and found there is something wrong with the wiring on the passengers side. The grounding wire for that switch is grounded but the power, assuming the orange is the hot wire, is not registering any volt when I test it.
At this point, I just want to by pass this connection all together. Meaning, How would I wire the courtesy lights to work if just the other two switches are tripped?

I am not sure what problem you are trying to solve or where in the wiring diagram or the passenger door and its wiring you need help with. I'll take a stab at what might be the issue.
There are a number of switches that signal door openings, key cylinder rotating and door handle lifting to the BCM for the purposes of forced entry security and courtesy lights. They are:
Drivers door: jamb switch, door handle switch, door cylinder switch
Pass fr door: door handle switch, door cylinder switch
both rear doors: jamb switches
If you are expecting a front passenger jamb switch there is not one on your truck. If that's not where you need help then tell me what wiring you are trying to figure out or what function you are trying to debug.
