I am having the exact same problem with my '05 model ... and more.
I have a 2005 Chevy Malibu Maxx LT (87,000 miles) with what appears to be a ghost! My power door locks "go crazy" by locking and unlocking themselves continuously. This happens while driving, parked, and even with the car completely shut off. I have often locked the car at night, and come out in the morning to find it had unlocked itself. This is an intermittent problem that will occur for a week, then not happen for a week or so... repeat.
The power lock buttons on both driver and passenger side do not work - I have to manually lock all 4 doors. The key fob will not lock or unlock, but the panic button does work. I can unlock the doors (driver, all and hatch) from outside using a key, but cannot lock them in this manner. This problem occurs consistently, whether the "crazy ghost" is at work or not.
I believe there may be a connection to another problem with my battery dying when the doors are left open or accessories are left on for 5-15 minutes without the car running. This happened consistently for a few weeks, but has "magically" stopped.
My alarm also automatically arms itself. I can close the door and open it again 5 seconds later and the alarm goes off.
In addition, my front passenger turning signal lamp will not work. The bulb has been replaced twice. The first time it worked for 3 days, then blew again. The second replacement bulb never worked once.
But wait, there's more! The Information Center randomly says "Low Coolant" or "Check Gas Cap" when there is no problem with either...
Could all this be related? Hopefully a simple wiring problem or short somewhere?

Sounds like your body control module (BCM) has gone south. We had the exact same problems with our '98 Chrysler minivan and replaced the thing and later had it rebuilt, $800 for new one from the factory, $225 to rebuild it recently through DirectAuto.com.
It may be a relay or fuse(s), if you want to try swapping similar relays around and check fuses, go for it, but with electrical things I suggest just going straight to a reputable, independent auto electric shop. Good luck!

Thank you for the reply!
Since my last post I have checked the fuses - all seemed ok, except the fuse-style resistor for the key cylinder just fell out. Funny thing, the key cylinder lock still worked without it!?! I also pulled out the trim panels in the trunk looking for a chaffed wire... all seemed fine there too and I couldn't get the locks to click by wiggling wire bundles. However, wiggling a wire near the battery in the engine compartment caused the security system to go into lock-down mode with a relay clicking somewhere for a good half hour (horn fuse was pulled, TG!) - pretty suyre that was unrelated.
All signs now are pointing to the BCM, as you suggested. I have an appointment with the dealer on Monday. I will followup with the official prognosis for others looking into similar problems!
Thank you again!

I HAVE A RECURRING PROBLEM WITH AN '05 MAXX AND IT'S BRAKE LIGHTS. THEY COME ON WHEN THE BRAKE IS NOT APPLIED, BUT DO NOT COME ON WHEN THE BRAKE IS APPLIED! THIS DOES NOT HAPPEN ALL THE TIME, BUT WILL BE A BIG PROBLEM AT THE WRONG TIME WHEN SOMEONE HITS ME FROM BEHIND. HAS BEEN WORKED ON TWICE, BUT STILL HAPPENING.
#169 of 254 Headlight Housing Mounting Hardware
Apr 02, 2009 (5:31 pm)
The passenger side headlight housing on my '06 Maxx is vibrating while driving and causing the light coming out of the bulb to "shimmy". There are two bolts at the top of the lamp housing which hold the housing tight against the radiator support. The bottom of the lamp housing has two "posts" or pegs which line up with and fit into two square holes in the sheet metal behind the housing. There is a good deal of space between these two "posts" and the inside of these two square holes, which is why I'm able to move the bottom of the lamp housing up and down.
Is there some kind of clip or fastener that I am missing which are supposed to attach to these two square holes in the sheetmetal which are supposed to hold these two "posts" firmly, in order to keep the bottom of the lamp housing from shaking?

First thing to check is the brake light switch. It may be defective or have come loose. Good luck.

Both of my headlamps were doing the same thing on my 05. I used double sided tape on the ledge the headlights sit on where the posts go through the holes. Worked well for me. Others I've heard have found rubber grommets at the hardware store that make for a tighter fit for the posts.

I also believe there are two metal tabs...careful they are sharp..that can be bent forward to hold the pegs/posts at the bottom....you have to feel around for them in the frame.....so has been posted on here before

I know that there are two sheet metal tabs below the lamp housing that coincide exactly with the position of the "posts", which are part of the lamp housing. In fact the two posts line up with these sheet metal tabs and are centered within the square holes in these tabs when the lamp housing is installed. It just seems like there is some hardware missing...similar to the nuts that are mounted on a clip of some sort, when you're attaching sheet metal underneath the car or like they use on the splash shields under some GM cars. I guess I could probably try cutting a small length of vacuum hose and slip that over the posts to make up the difference between the inside of these square holes in the sheet metal tabs and the outside diameter of the lamp housing posts. I suppose I could also remove the drivers side headlamp assembly to see what is used under it, since it doesn't exhibit any of these vibration symptoms that the passengers side lamp housing does.
#174 of 254 replace dome light assembly
May 08, 2009 (4:34 pm)
I need to remove the dome light base from the headliner without wrecking the headliner. My dome light switch melted and the switch is included in the base. I've got the bezel and cover off already. Help?
