random door un-locks and trunk release

I've searched far and wide and have yet to find a potential solution to my problem... The doors on my 2004 GAGT randomly unlock. Sometimes its just the drivers door, sometimes its all four doors. The trunk occasionally pops open as well. I've checked the bcm, its connectors and the drivers side fuse/relay panel for water, and everything seems to be dry. Any other suggestions?

Thanks for the suggestion. I opened up the relays yesterday, and they're spotless inside. I also lubed the connectors with di-electric grease, but my doors still unlocked on my way into work this morning.

Replaced my nearly 7 year old battery, and haven't had the problem since...

Never had any trouble starting... Just the issues with the door locks and the trunk.

Well, the issue disappeared for about 2 weeks after replacing the battery. Now it's happening again. Alternator possibly?

My trunk used to pop occasionally too, I replaced one of the fuses in the drivers side fuse box and it went away. Have you checked to make sure none of the fuses are blown?

I haven't, because it seems nearly impossible that a blown fuse could cause the trunk to open and the doors to unlock.

If you have the factory red boot on your positive terminal cut that off. Id be that moisture has been getting in there and corroding it from the inside out.

My car would click the trunk relay (but never opened) and after cutting that boot off and replacing the terminal which was beyond saving everything was back to normal.

Remove it to see if the issue is with the car or with the aftermarket equipment. I've seen aftermarket equipment (especially when the installer thinks tape 'n scotchloks are primo technology) cause goofy stuff like this. Does this happen everywhere, or just in certain locations (any chance of interference from other devices?). As has been said, dirty connections in the electrical bus can cause weird stuff as well - the comment that the problem abated for two weeks after battery replacement supports the idea you've got a nastified terminal at the battery.
