Gremlins ! No ! You want to know how this is possible ? The ignition switch is a low voltage input to the BCM - body control module ! Going by which position you have the key in ACCY , ON , run or start . The BCM system will control relays to turn on power to different parts of the vehicle ! The place to start would be to hook up a professional type scan tool that can communicate with the BCM . Could have U codes stored in one or more of the modules on the vehicle ! Do you know what a power mode master PPM is , BCM !
BCM Functions
The body control module (BCM) performs multiple body control functions. The BCM can control devices directly connected to its outputs based on input information. The BCM evaluates this information and controls certain body control systems by commanding outputs on or off. The BCM control inputs can be:
• Sensors and switches that are directly connected to the BCM
• Class 2 serial data received from other vehicle systems connected to the class 2 serial data link.
The BCM is also capable of controlling other vehicle systems that are not directly wired to the BCM. The BCM does this by sending specific messages on the class 2 serial data link. The system capable of performing the required function will respond to the BCM message.

Your best bet would be to take your vehicle to a Buick dealer !
Power Mode Master
This vehicles BCM fuctions as the Power Mode Master (PMM). Refer to Power Mode Description and Operation for a complete description of power mode functions.

The security system (VATS/PassKey) is faulty. You can find a great write-up here: http://newrockies.ca , it was the only thing that saved my Park Avenue.

SOURCE: The door chime on our 2005 Saturn Relay Van

I have a 2006 SV6 with the power sliding doors. The problem that I found was with the contacts on the door ( They are called plungers) the movable pins were losing connection with the fixed part The plunger is very easy to replace if you can find one. The plungers are covered with a rubber cover and is held in place with 2 plastic pins. My Pontiac dealer could not even find one in his books or even a picture of one, and claimed that he had never had anyone come with a door problem. My Chevy dealer said that it came with a wiring harness that is not needed for $154. The cure that I came up with was to take the plunger block apart (it snaps together)and replace the rusted out springs then solder 3" wires to the end of the plunger pins (they solder easy) to the tabs that go to the plug(pop out the tabs or you will melt the plastic. It took about 45 min. now the doors work like new and will never loose contact again

How do I disconnect the chime from automatic door .Had to cut cable as it jammed . Took out fuse but radio and clock now do not work .Can I disconnect wire from chimes .I knoe it comes from speakers .


try this
disconnect battery
undo the fuse box and look at the wires behind that fuse you pulled

check that only radio and clock wiring are fitted there

the chime may its own power source

i could be wrong
i thought chime was separate to sound system speakers
and comes from a small but loud sound device on the instrument panel circuit board ..much like a computer

Why does my Buick Park Avenue give a warning chime everytime the door opens with the engine off. (The lights are off)


Are the keys in the ignition, or have you left something turned on?
Usually this is a warning that you have forgotten to do something important, like perhaps turn off your stereo, take out your keys, turn off a light somewhere, put your gearbox into park, apply your parking brake etc. Please re-check EVERYTHING and if nothing is a miss then please report.

sounds like theres a problem with the ignition switch or the cylinder lock,your going to have to unplug harness connection under dash to see if radio goes out with the chime if it goes out when unpluged then the problem is in ingnition system, most likely its a jammed key sensor in cylinder, start there hope this helps,

When I turn the car off,and pull the key out,the radio light comes on and I can play the radio also.if I open the door,it all shuts off.What is wrong?


The feature is called "retained accessory power" or RAP for short. The purpose is to allow accessories such as the radio, power windows and blower functions to continue for the drivers convenience after the key is turned to the off position or the key is removed. The RAP feature will remain active for 20 minutes or until the drivers door is open which ever occurs first.
Hope this explains it for you.

Hi! I have a 2002 Cadillac Deville and yesterday I unlock the door with key pad and opened it and when I did I heard the chiming sound that it makes when you have the keys in the ignition with the door...


It may be trying to get your attention for an open door, trunk lid or other item requiring attention. Check your owner's manual for items that can cause it to chime.
