Anyone like puzzles? If so read on...

Take car to store ( >5 mi away ) Lock car - everything normal.
Get in car drive back. MSP light goes on by itself. (Unable to shut off with button )
Park in garage- turn car off, turn back on MSP light is off and button allows for toggle.

I go to lock the car, it chirps and 2 seconds later unlocks itself yet the alarm stays on and active.

I have opened and closed all doors + Hood + Trunk. Center armrest is closed.

...a dozen times later still [press key or via the door] it locks - chirms - arms and then ... ( wait for it... ) it unlocks and stays armed....


Anyone have any ideas?

I have tried dc the battery, ( while dc it does lock ) however once hooked up it no longer locks.


It does lock when using the passenger side inside lock, yet not from the driver side.

...Oddly enough, I can lock the car via the pass side door.

Anyone know if a relay or seperate fuse etc that drives the doors seperatly?

The Car was at the dealer for 4 hours today... Still no answers, they are ordering the locks and motors for the doors to "swap" parts to see what the issue may be....

The dealer is taking their sweet time in getting in the parts.

They have ordered both locks (modules) as they are puzzled which one it is; or if that truly is the problem. The response was that the driver side lock scans the pass side and reports to the ECU as to position. If it cannot confirm the status it 'tries' again. This may repeat up to 10-12 times; ( hence the fast click, click unlock/relock sound)
They charge an hour of labor to remove each, yes each panel.

Here is a quick check that I have found to isolate the problem:
• Roll both windows down

• With your hand first check to see the power actuator works by pressing the button on the inside of the door to get it to latch. Start with pass side and take note if the driver side locks at same time or if only one does. Do the same from the other side. (UNLOCKING after each test)

• Now start with the pass side and use key (toward back of car) take note if opposite side locks.

• Next with remote lock the car and see which inside lock switch clicks open and goes back. The issue is in the opposite module.


What I have found is that each door alone locks via both methods; however the locks do not communicate as they should.
My driver door locks for a split second and the pass side does not report back.
(The piece ordered was for the pass side).


Once in, I'll advise how it works out.


I'm still puzzled how this all of a sudden is 'bad' the car had been in the garage, never ever exposed to rain, no other electrical issues.

...Fixed

The doors are back working again thanks to a new pass side door module. Each module "looks" at the other side to confirm the open or closed position. Any communication error between the two causes the instant unlock.

First time back on in a bit.

I ended up having the pass side door module replaced. The unit ran about 200; labor 300.
