Passenger side door lock isn't locking

Important: If all 3 passenger door locks are inoperative from both door lock switches, test the unlock control circuit between the splice and the BCM for an open.? Do you know how to do this ? Looking at a wiring diagram an using a DMM - digital multi-meter ?

Did you perform the Diagnostic System Check - Vehicle?
Go to Step 2
Go to Diagnostic System Check - Vehicle
2
Verify that the Power Door Locks Inoperative - Passenger Door fault is present.
Do the door locks operate as described in Power Door Locks Description and Operation ?
Go to Testing for Intermittent Conditions and Poor Connections
Go to Step 3
3
Are all 3 of the passenger doors locks inoperative from both door lock switches?
Go to Step 10
Go to Step 4
4
Install a scan tool.
Close all of the vehicle doors.
With the scan tool, observe the Right Front (RF) Door Lock Switch parameter in the Data Display, Inputs list of the body control module (BCM).
Operate the front passenger door lock switch to both the LOCK and UNLOCK positions.
Did the parameter change to both the LOCK and UNLOCK states?
Go to Step 7
Go to Step 5

Important: If the 3-amp fuse of the jumper wire opens when the jumper wire is connected, test the appropriate signal circuit for a short to battery positive voltage.
Disconnect the harness connector of the front passenger door lock switch.
Connect a 3-amp fused jumper wire between the lock switch lock signal circuit of the harness connector and a ground.
Observe the RF Door Lock Switch parameter.
Connect the 3-amp fused jumper wire between the lock switch unlock signal circuit of the harness connector and a ground.
Observe the RF Door Lock Switch parameter.
Did the Scan Tool parameter change to the both the LOCK and UNLOCK states?
Go to Step 6
Go to Step 8
6
Connect the 3-amp fused jumper wire between the lock switch lock signal circuit and the ground circuit of the harness connector while observing the appropriate Scan Tool parameter.
Did the Scan Tool parameter change to the LOCK state?
Go to Step 11
Go to Step 14
7
Disconnect the harness connector of the inoperative door lock actuator.
Connect a test lamp between the door lock actuator lock control circuit and the door lock actuator unlock control circuit of the harness connector.
Operate the front passenger door lock switch to the LOCK and UNLOCK positions.
Did the test lamp illuminate in both positions?
Go to Step 13
Go to Step 9
8
Test the signal circuits of the front passenger door lock switch for a short to ground or an open. Refer to Circuit Testing and Wiring Repairs .
Did you find and correct the condition?
Go to Step 18
Go to Step 12
9
Test the lock control circuit of the inoperative door lock actuator for an open. Refer to Circuit Testing and Wiring Repairs .
Did you find and correct the condition?
Go to Step 18
Go to Step 10

Important: If all 3 passenger door locks are inoperative from both door lock switches, test the unlock control circuit between the splice and the BCM for an open.
Test the unlock control circuit of the inoperative door lock actuator for an open. Refer to Circuit Testing and Wiring Repairs .
Did you find and correct the condition?
Go to Step 18
Go to Step 12
11
Inspect for poor connections at the harness connector of the front passenger door lock switch. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs .
Did you find and correct the condition?

Go to Step 15
12
Inspect for poor connections at the harness connector of the BCM. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs .
Did you find and correct the condition?
Go to Step 18
Go to Step 16
13
Inspect for poor connections at the harness connector of the inoperative door lock actuator. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs .
Did you find and correct the condition?
Go to Step 18
Go to Step 17
14
Repair the open ground circuit of the front passenger door lock switch. Refer to Circuit Testing and Wiring Repairs .
Did you complete the repair?

Operate the system in order to verify the repair.
Did you correct the condition?
System OK
Go to Step 2

remove door panel and check linkages

Sounds like the main wiring loom into the door has been damaged.
Check near the hinges, where the door swings, to see if any damaged wires. Does the door lock and unlock from the drivers side switch?

It could still be the relay, if the solenoid is working but the contacts are faulty. There are also several other places in the circuit which could cause this. Follow the diagnostics from p90 on, here

faulty master switch ..replace

looks like car has other issues as well.. but try that first

door lock actuator might be faulty or bad electrical contact
take off the door panel and diconnect and reconnect the wiring, you might need to change door lock actuator

You can usely find the parts on eBay easyer then the regular parts stores...I looked for these before...they are ready available...

hi, does the drivers door unlock and lock all the other doors if it does then you may find that a clip or connecting bar has come off the passenger door lock, you would need to take the door panel off to check,

If how ever the passenger door dont lock and unlock via the drivers door then you would need to buy a new central locking motor for the passenger door..

Your best option would be to remove the passenger side door panel and get someone to lock and unlock the drivers door whilst you look at the passenger side and have a look to see what parts are moving this should then give you a good idea of the parts that could be damaged

Generally fuses control an entire system, in this case it sounds as if you have a wiring problem such as a plug has come undone that wires the door equipment. Check the wiring that goes to the door, follow it to your problem.
