2007 Saturn Vue interior lights and alarm

[LarsMac]

This just recently began.
I park and lock the car. Alarm goes of at some time.
I can stop the alarm with unlock from remote. However, interior lights remain on. If I lock the car, at some point the alarm sounds.
Leaving the car unlocked, alarm never sounds.
For tonight, I have disconnected battery.
Need to figure it out in the morning. Any suggestions would be welcome.

Well, this AM, All is normal.
This thing has been bugging me for three or four days, now, but this morning, it's like I imagined the whole thing.

I am currently thinking that the switch in the side of the dashboard that appears to control the interior lights when the door opens and shuts, might be loose, or moisture got into it.
But now, I have to wait for it to act up, again.

I got to say, though, for 140 k miles on a 17 year old car, this is the first problem that I've run across, I reckon that I've got nothing to complain about.

Well, all day, not a peep. Until about 6 PM, then just now the alarm started up.
Hit the unlock on remote. Alarm stopped.

No sign of water intrusion.
Going to look for signs of mice. That's a possibility, though I never leave food in the car.

We're in a rural area, so mice can be an issue.
not worried about burglars and such.
It does get windy out here, so possibly motion sensor tripped? We been out here for going on five years, and wind has never triggered the alarm. Even being battered by hail storm didn't trip the alarm.

I'm going to use this as a log, if anybody runs across the thread and has some suggestions, I'd welcome them.

Monday - 4 Aug
no further event after alarm trigger last night.

Spent morning inspecting for mice or other critter intrusion. nothing, so far.
checked all doors hood, and rear hatch for proper opening, closing an latching.

Set lock. Waiting.

very light breeze, so far.

Today, the thing was quiet most of the day, until around 3:30 or 4, when the temps got up in the 90s.
When the alarm sounded, first time, I hit the unlock button on remote. The driver's door unlocks and the alarm stops.
I re-locked, and left it.
about half an hour later, sounded, again. This time I hit the alarm (red) button, alarm stopped. after a couple minutes, I hit the unlock button, and the car beeped three times. and the door unlocked.
I went through the car, checking all the doors(again) looked for signs of rodents or any other critters. (again)
The only thing I can come up with is that somehow the car detects motion from the wind blowing and it sets off the alarm. But there is no consistency to that, and I would expect that I could also set the alarm off by bumping and pushing on the car. No luck there.

Well, other than logging the issue, it seems posting here is a waste of time.

All the weird behavior I encountered initially seems to have ceased.
The interior lights no longer remain on, and alarm does not sound while I'm driving, Everything seems to be have as expected, other than that the alarm can sound randomly while the car is parked and locked.
My only guess, at the moment is that one of the contact switches (Probably the Driver's door) is faulty? I'm will figure out how to get under the dash and try to test that.

[LarsMac]

Well, ...,

The symptoms ceased, as mysteriously as they began.

Not a clue what started it, nor, what may have changed to finish it.

Possibly some random water intrusion, that eventually dried up?
Mouse intrusion? no signs.

I dunno. :shrug:
