Question about 2003 Hummer H2

1 Answer

Rear door lock states its "open"

The switch or something on the right rear door is locking and closing but on my dash it says its open, and i believe that because its reading as open that the electronic rear air shocks wont pump up either because they dont activate with a door open- what might the problem be(with the lock signal), and where can i find that sensor for the door/lock?

    I am as well having this issue. I was able to slam the rear door really hard and the dome lights would turn off. Now it doesn't bother turning off at all. I'm not sure how the door system works, but I'm plan on taking the rear door apart and looking for the sensor.

Does the 2009 CR-V have a door jamb sensor for the tailgate? Tailgate light is on, on dash. Doors won't lock with FOB or while moving. Tailgate closes, locks and unlocks, it just thinks it's open.


Sounds like a bad switch on the tailgate. Open your tailgate and look for a switch. When you find it...press it in completely and see if the sensor light goes off. If so, replace it.

2003 h2 hummer right rear door sensor switch must be sticking dash reading says it ajar I open and shut that door and all others few times but no luck


You can try spraying WD-40 directly into the striker section of the latch and open and close the door several times to try and free the switch up, but even if it starts to work again, it is just a temporary repair. You will need to look to getting the latch replaced soon.

How do i fix it the problem with the sensor on back passenger door it shows up on dash board as door is open


Many door open sensors self-adjust the first time the door is closed. If something gets between the door jamb and the button switch, the switch can get pushed in too far to actually make the connection when the door is closed.
You may be able to pull the switch back into normal position, or at least replace the switch.

all the lights above the dash do not work ?????? DOME light's ??? No light's come on when you open the door or any door ? Wouldn't think all the door ajar switches bad at one time .
Interior Lamps
The interior lamps consists of two groups, lamps that can not be dimmed and lamps that can be dimmed. This first group consists of lamps that may not be dimmed. This Includes those lamps that may be manually turned on by placing the interior lamp switch to the DOME position, or by opening a door or a compartment:
• Auxiliary dome lamp (SEO, RPO 6C7)
• Dome lamp
• instrument panel (I/P) compartment lamp
• Inside rear view mirror lamps
• I/P courtesy lamps
• Reading lamps
• Rear compartment courtesy lamp
• Sunshade vanity mirror lamps
Battery positive voltage is applied at all times to the DIC/RKE fuse and to the switched side of the BATT RUNDOWN PROTECTION relay in the right I/P junction block. The DIC/RKE fuse supplies battery positive voltage to the coil side of the BATT RUNDOWN PROTECTION relay. When the ignition is turned to the ON position, the body control module (BCM) provides a ground to the Inadvertent relay control circuit. This energizes the BATT RUNDOWN PROTECTION relay and applies battery positive voltage to I/P BRP fuse and to the TRK/ROOF/BRP fuse. Battery positive voltage is applied from the I/P BRP fuse to the I/P courtesy lamps, I/P compartment lamp and to the I/P compartment feed circuit to the BCM. Battery positive voltage is also applied from the TRK/ROOF/BRP fuse to the:

If the BCM receives a door lock or unlock input signal, the BCM will activate the BATT RUNDOWN PROTECTION relay, which provides battery positive voltage to all interior courtesy lamps. When any door is opened, the door jam switch contacts close and the BCM receives a door-open input signal. The BCM then applies a ground to the theater dimming ground control circuit illuminating the courtesy and dome lamps.
After all the doors are closed, the courtesy lamps remain illuminated for approximately 40 seconds. The courtesy lamps will also turn on and remain illuminated for approximately 15 seconds after the ignition key is removed, prior to any door being opened.
When the headlamp switch is placed in the DOME position, the BCM receives a ground signal. The BCM then applies a ground to the theater dimming ground control circuit. This illuminates the dome and roof rail lamps.
The courtesy lamps will normally turn off using the theater dimming feature. The BCM provides a pulse width modulated ground to all courtesy/reading, dome, and inside rear view mirror lamps for the theater dimming feature. The BCM will immediately turn off the courtesy lamps if a door lock command is received with all the doors closed, or if the ignition switch is turned to either the ON or RUN position.
The BCM activates the interior lighting output 15 seconds after receiving the class 2 message "Airbags Deployed" from the sensing and diagnostic module (SDM). The interior lamps remain activated for 25 minutes.

The door ajar switch is part of the lock actuator inside the door !

1998 safari rear door lock / power locks


This problem can be caused by a few things, it could be the rear door lock switch or lock module located under the dash or last the rear door actuator.

You say that all door lock and unlock on there on, this tells me it most likely has a module problem or wiring to the rear door is bad.
The first thing i would do would be to remove the rear door panels and check wiring to switches and actuator, then follow wiring from inside the rear hatch to where in goes through the body. the wiring most times breaks at that point where the wiring is bent over from opening and closing rear door ,

Locate the wiring going into door or doors. sometimes the wiring only goes into one door but then sometimes in goes into both doors, check the wiring closely . it may be covered in a rubber boot . if it is covered you will need to slide boot back to check wiring.

Good day. hope this is helpful.

Rear access door ajar


What's your question ? Tailgate ajar light lit on the instrument cluster ?
The Body Control Module (BCM) monitors the lift glass and the cargo door ajar switches. When the switch closes, the path to ground is completed, and the BCM sends a class 2 message to the instrument cluster to display the CARGO DOOR AJAR message.There are two ajar switches for the rear door ,a left an a right ,the third switch is for the lift glass ajar switch . All three of these switches splice pack SP410 At ground point G410

(Shouldn't have any readings when door(s) and/or window closed.) It's the opposite . switches are open with door closed , G410
In the Body Harness, Behind the RR quarter trim panel near the D-Pillar
It turns out it has nothing to do with rear door. Something about drivers door actuator. NO IT DOESN"T !!!!

The passenger rear door on the left will not open...


I don't believe I have seen a Volvo four door hatch-back here in the US, but my guess would be child-proof locks on the rear. Open the front doors and look for any switches on the front edge of the back doors. If there aren't any, check the owner's manual before contacting your dealer.
