Rear access door ajar - false signal - Fixya

www.fixya.com/cars/t22610885-rear_access_door_ajar_false_signal

Most panels are held in place with clips attached to the underside of the panel. There may be screws as well attached to any handles used to lower the gate. If all screws are removed, pull on panel and the clips will release

Check it out on you tube !

try open the left back door first then the outher one

I purchased a 2005 Quest that had same damage on the rear lift gate. If I crossed my eyes and pressed down on the magic spot 3% of the time I could get the door to close in a way the sensor would recognize so I didn't have the door open light turn on.

Too fix this problem I removed the interior panel from the lift gate which allows access to the the lock and some of the wires. almost directly behind the licence plate you have access to the inside the lift gate you should see 2 wires that appear to be going down the latch. I'm assuming one of these controls the power locks and the other is for the feedback sensor that tells the car the door is open.

on the drivers side of the opening that exposes the wires going down to the lock you will see there is a white connection for 1 of the 2 wires that is mounted to the inside of the lift-gate. All I did was squeeze and separate this connection and the car no longer recognizes the door is open.

I don't have an alarm so I don't know if this would mess up the alarm other than if someone broke in through the lift gate it wouldn't trigger the sensor.

I hope this helps

Replace the bulb,
1. Open the lift gate on the rear of your Blazer or drop it if you have the tail gate that folds down. Locate the screws on the inner edge of the lift gate frame. There are two screws--remove them with a Phillips screwdriver.
2. Slide the taillight assembly out of the rear of the truck, being careful to not break the locating tabs on the rear of the housing. Locate the bulb sockets on the rear of the taillight assembly.
3. Rotate the light bulb socket counterclockwise about a quarter turn to unlock it from the taillight assembly. Pull the socket straight out of the assembly with the bulb attached to it.
4. Remove the bulb from the socket by pulling it straight out of the socket. If you are removing the entire assembly from the truck, remove the remaining sockets from the rear of the taillight assembly, lay them aside and remove the assembly completely.
5. Reinstall everything in revers and don't for get to *** some grease to your socket before you place the new bulb in place and test the operation of the new bulb before you reinstall the tail light.
Thank you for using fixya and here is the bulb you need for the trail light.The 1999 Blazer uses a 3057 bulb available at most auto parts stores.

I have a 2001 Sienna and have had to replace most of my tail light bulbs.

The bulbs that are mounted in the fender (wrap arounds) have acess panels in the van's interior that easily pop out and expose the back of the light assembly.

However, the bulbs that are found in the lift gate are a different matter. You have to remove the whole interior panel to the lift gate to expose the light assemblies. Go to your auto parts store and get a tool to help pop out the plastic retainers from the lift gates metal frame. Don't force the retainers out. Go slowly and gently so that you don't damage the interior panel. If you are really gentle you might even get to reuse the retainers.

Good luck!

Hello
The sensor your looking for is on the latch for the lift gate
you will need to remove the lift gate panel to access this it has a single wire switch
