I've got a 2005 G6, something tripped the anti-theft system last night. Now the car is telling me that a door is ajar when no ajar door can be found and the interior lights won't go off.

Does the alarm system need reset to fix this problem? Or am I just too weak to close a door?

Even when i arm the car the interior light stay on.... and the doors wont lock... please help....

I did a search and found no items with the same issue as i have... :-(

Here are the steps taken:

open car door and sit i it for 10 minutes (interior lights stay on for all 10 minutes) not automatically arming itself.

2 start the car, you hear a chime "Door Ajar", i press the Door Lock button, all doors lock except for the Driver side door, stays open "door ajar"....

turn ignition off, and stay in car waiting for alarm to arm itself, nothing.... i have to use the Stock Dongle thing to lock the doors, have to press the lock button twice in order for the doors to lock..... then i arm the car with the Python....

Any help would suffice. i personally think it's the alarm system and not the door issue....

I'm thinking the driver's door sensor is bad. Let's think about it logically...

What makes the car alarm go off: Either 1. One of the doors is opened once armed without using the Remote Keyless Entry, 2. The hood is opened on cars with remote start, or 3. I think it's the trunk but I can't remember...

I think 1 is the scenario you have...

In addition with the DIC saying door ajar...The car somehow thinks your driver's door is open

In additon to the doors not locking when you hit the lock button. The car is locking all the doors then reopen the driver's door because it believes that the driver's door is open and it doesn't want you to lock your keys in the car. Hint: if you hold the lock button down for like 3-5 seconds it'll override that saftey feature.

The only thing I'm not sure is how about the sensor went bad in the first place, especially if it was just sitting in your driveway...unless some idiot was trying to open your car door and just managed to damage the sensor.

In conclusion I believe it is a door sensor thing, NOT an alarm thing. Then again I could be totally wrong.

Also, I'm no shade tree mechanic so I'm not huge help fixing it, just trying to point you in the right direction.

WTF...

So i call the tech @ GM, and he tells me, "you have a batch Latch but we're not sure which one"....

I say, "yeah i told you i have a bad latch, but it shouldn't take over 48 hours for you to determine which latch it is.....

I been car-less for 48hours +.... and they "Still" haven't determined which latch it is... I need my car before the weekend, if it is not done by tomorrow i will go pick it up, order the parts online and do the shit myself......

Oh, now i am fricken pissed off....

the guy called me and says that i have a bad latch, but..... they don't know which latch is it because of my after market alarm system... they asked me to take it back to the alarm place and have the alarm removed and then bring it back....

Seriously.. WTF....

I'm ordering 2 latches today from Pontiac and taking to my local guy and have him install for 50 bucks each.... not a happy camper....

Yes, I know of the bad sensor issue. Had one last week and now another one this week. I'm not kidding. My car has 87,000 mile on it and this is the first major issue it has had. There is a unit inside of each door that tells the computer system that the door is ajar. A simple diagnostic test can be run to determine which sensor has gone bad. The problem is there is one for each door and each costs about $250 to replace. Pretty expensive, annoying problem. Yes, the interior lights are connected to this. I think they also control the lock of the door. I've had an issue with that as well. These are bad everywhere it seems. I wonder if GM will recall or reimburse for this issue?
