Inoperative Left Door Outside Handle Switch (If the door handle sticks in the open position for longer than one minute, the door will not
open and diagnostic code B3849 will be set if the failure was less than 50 ignition cycles prior to checking codes)
1. Remove the window switch, Refer to Door Lock and Window Switch Replacement Driver Side (DDM) in SI.
2. Disconnect the door lock/window switch-driver (DDM) X6 connector.
3. With a DVOM connected to ground and pin 2 circuit 5881 in the door lock/window switch-driver (DDM) X6 connector, the readings should

be less than 20 ohms with the handle in the open position.
4. With a DVOM connected to ground and pin 4 circuit 5882 in the door lock/window switch-driver (DDM) X6 connector, the readings should
be less than 20 ohms with the handle in the open position.
5. If resistance is higher, remove the door trim. Refer to Front Side Door Trim Panel in SI.
6. Check the resistance at the doc-n-loc X505 female connector, pin 11 circuit 5881 and pin 2 circuit 350. Reading should be less than 20 ohms
with the door handle in the open position.
7. With the handle in the open position the resistance should be less than 20 ohms on pin 12 circuit 5882 and pin 2 circuit 350. If the values are
correct at the X505 connector continue with Step 8. If the values are incorrect, proceed to Step 14.
8. Relocate the wiring harness by moving it away for the doc-n-loc on the trim panel and apply duct tape to the harness.
9. The doc-n-loc is out of position, remove the upper doc-n-loc connector from the bracket. The white connector housing has six tabs that have
