Who looked at it ? Dealer ? Did the place's you had look at the vehicle hook up a factory scan tool an view data to door module's an the BCM ? Door ajar is a fuction of the door modules an the BCM - body control module . One of these modules is seeing an input that makes it think door is open .
The door ajar indicator system consists of the following components:
• The driver door module (DDM)
• The passenger front door module (PDM)
• The body control module (BCM)
• The instrument panel cluster (IPC)
• The driver information center (DIC)
• The driver door ajar switch
• The passenger door ajar switch
• The left rear door ajar switch
• The right rear door ajar switch
• The liftgate ajar switch
Driver Door Ajar And Passenger Door Ajar
The DDM and PDM receive a discrete input from the respective door ajar switch to indicate the status of the door. The DDM or PDM then communicates this status to the IPC via class 2 message. The IPC, upon receipt of this class 2 message, will illuminate the appropriate door ajar message in the DIC and also send a class 2 message to the radio to activate the door ajar audible warning when the following conditions are met:
• The transmission is removed from PARK
• The vehicle speed is greater then 8.05 km/h (5 mph)
Left Rear Door Ajar And Right Rear Door Ajar
The BCM receives a discrete inputs from both the left and right rear door and liftgate ajar switches to indicate the status of the doors and liftgate. The BCM then communicates this status to the IPC via class 2 message. The IPC, upon receipt of this class 2 message, will illuminate the appropriate door ajar message in the DIC and also send a class 2 message to the radio to activate the door ajar audible warning when the following conditions are met:
• The transmission is removed from PARK
• The vehicle speed is greater then 8.05 km/h (5 mph)
Could have DTC'S - diagnostic trouble codes . Looking at data paramiters on the scan tool tool would show what switch is faulty or what part is .

It would be on the left header pipe as you sit in the truck. Its the sensor in front of the cat

Wayne, the only diagram that you will find is a parts breakdown at the dealer. They will blow it up for you on the computer screen. It sounds like the rod has come out of the lock mechanism, if so its a small plastic clip that holds it in place. You can pick one up at a local parts store in the "help"section. Good luck, dont forget to rate.
SOURCE: remote starter does not work but will unlock and lock doors.
this function is preformed through the Body control module, this can be tested for faults by the dealer only.

depending on your alarm which it sounds like a viper model maybe? on my 02 you have to incorporate a factory alarm bypass module in order to be able to start the truck, they run about 100.00 bucks and have to be profssionally installed. The truck wont start because the computer isnt recieving the proper starting sequence due to the factory alarm
