Door ajar switch again !!!
I've been torturing myself with this problem for 2 months. I'll give the quick run down. First , 2006 F-150 STX 4x4 supercab 4.6 v8. No PW,PL.
I've removed both door switches, still chimes. I went to forums here and removed rear seat back looking for BSM, it's not there. Can anyone tell me where the BSM is on this truck. I'm bound and determined to fix this myself. I don't want to go to the dealer.

Without RKE ( or Autolamps ) there is not a BSM / VSM installed.
What You have is the Door ajar switch to the Instrument cluster direct.
The door ajar switch, switches ground ( & no ground ) to the instrument cluster for the door ajar & interior lamp operation.
Reinstall the door ajar switch.
In the wire loom from the driver's side door to the a-pillar ( access just inside the a-pillar, driver's kick panel ), check the black w/yellow stripe wire. It should have ground one way, and no ground ( nor power ) the other. Test with a meter to a know good ground in the driver's side kick panel using the resistance or continuity setting.
If the circuit does not change, it could have a short to ground or be open ( depending if it is always ground or always nothing ).
