My car alarm randomly goes off. It's not the one associated with the battery. A while back I needed a new key clicker (unlock lock thing) and somehow got stuck with two alarms? One I can't control that goes off when the battery is disconnected. The one that's going off right now is from my clicker. Doing this past six months and a lot more recently...

introduce the next issue...

My doors auto unlock and lock and that beeping noise that a door is open sounds at random times usually on turns when I'm driving.

Another thing I noticed. Usually when I turn the car off I can still roll up the windows etc. until I open the door then everything shuts off. But now pulling the key out everything shuts off before opening the door.

My coolant seems to disappear very quickly. I haven't tested out how many days but it seems to run out fast.

Side note: Am I suppose to have this many fuses missing?

 

Well for the fuses it depend on what accessories your car has on it. You can check the book to see what each fuse goes to and check that way. As for coolant, do you notice any of it under the hood? If so you probably have the infamous radiator leak a lot of us have. I just had to get mine replaced. Also if you do not notice any coolant under the hood ya might want to check your oil cause it could be the head gasket. I would think that would make it run funny if it is and I would think you would notice it but who knows. As far as the alarm. Not sure what is going on there as mine just had the factory alarm that shuts off the car and sound the horn ect. Did you take it somewhere and they installed another one for you? Hard to say from what you describe. Anyway hope maybe I helped some. Good luck and keep us posted. Thx.

P.s oh and as for the door chime/Windows etc. could be you BCM (body control module) got wet or damaged as I think that controls that stuff.

 

I removed all the aftermarket alarm crap in mine, no issues now

 

It's likely your aftermarket alarm, and/or you did not get the fob properly relearned to the truck?

The OEM alarm can sound the horn when reconnecting a battery, but not always.

Since we are on the battery topic......... do you still have the OEM crappy azzed battery terminal connectors??? If you do, get rid of them for a set of quality aftermarket connectors, like Stingers or your favorite brand. Use the search function, lots of threads on chit canning the OEM terminals, they are a known open door to electrical Gremlins.

 

Dude! This was done at a dealership. I didn't realize until a year later new battery that there was the original alarm too. By then I was in another state so no going back and saying the heck? There are somehow two alarms and this main one sucks. The blue light thing doesn't blink anymore cuz that's for the original?? My current key fob has a ****ty non loud alarm so it's not annoying as much. Original alarm only goes off when disconnecting the battery. & its fkn loud... I have to wait for it to shush cuz my fob doesn't work on it.

Lol!! Ya I read about it terminal connectors and never got around to changing it. Oops.

As for radiator...no mechanic I trust. One guy said fan clutch and one said new radiator another both and another said only a new radiator cap. Freaking sucks. It was really the transmission I come to find. YAAA FML. I'm not even sure if anything else was bad. That's been rebuilt. Still have acceleration issues.

 

Blue light thing???? There is no OEM Blue Light thing for any alarm. The OEM alarm blows the horn, which on a stock H3 is super wimpy.

You might have more than one aftermarket alarms, which would be a cluster of a mess? Or possibly whatever alarm you have has more than one siren tone?

Might be time to find a local electronics/stereo automotive installer to have a look.

 

Agree with Doc, only alarm indication I have is the one on the dash which is red with a little lock/car symbol thingy. I think it might just be red, not sure if it is also amber at times, but no blue whatsoever. Whoever that dealer was that worked on your Hummer screwed ya big time. I also never heard of having an alarm on the key fob so that defiantly after market right there, maybe that one means the fob battery needs to be replaced? Anyway Good Luck!
