When opening the door, the glass does not go down, the electronics do not respond

[B0omFreSH]

Hello everyone! I am writing through a translator, as I do not speak English. I cannot find a similar situation as mine anywhere, I hope someone has encountered this and will help me.

Lately I have noticed that when I approach the car and open the door, the window does not go down so as not to touch the door seal. The car needs to wait a bit for about 3 seconds before the window goes down. But sometimes it is not 3 seconds, but 5, or 10, or even 15. It is a different time each time.

The same situation is inside the car. When I turn off the engine, take the keys out of the ignition and open the door, the window does not go down, the electronics in the car do not turn off, the multimedia continues to work. The car needs to be wait a bit for 3 seconds, or maybe 15, or even more than a minute (!) And when it realizes that it is time to turn off the electronics, the window goes down, the electronics turn off, the multimedia also turns off immediately.

This is a very strange situation, it has never happened before. There is no such problem with the passenger door. I don't even know what the problem could be, since I did not repair or climb into the car's electronics, or the door or the glass.

I will write that about a year ago I installed an alarm with a GPS module, but there was no such problem before. I will also say that about a month and a half ago I bought a new battery, but can it cause problems? I also disconnected the terminals, I calibrated the glasses - but none of this helped.

Most likely the problem is in the wiring or in the door lock itself, but maybe someone will tell me that the problem is something completely different. I don't want to get into the electronics and disassemble the door yet.

Thank you for your attention!

There are a couple of things that come to mind. First off you said you installed a "new" battery in the car, most people don't know that when you get a new battery from the store, they are NOT fully charged, maybe about 50%, or even less depending how long it has been sitting. I did research on that. If you don't drive your car EVERYDAY, it won't do much to charge your battery, as the alternator isn't designed to be a battery charger, but a maintainer. When the battery in these cars is low on voltage, weird things happen. I would put a full charge in the battery, after that is done, disconnect the negative cable for 30 minutes or so to "reset" the electronics, and see what happens. Another thing to check if you have access to an OBDII port scanner, see if there are any BCM, (BODY CONTROL MODULE) codes stored, if so, you need to look into them and see what's up. That's all I can offer at this point. Good luck!!

Have you tried to re-index the windows per the owner's manual?
Just a thought, although the other problems you're having probably complicate the issue!

Thanks for your advice! As for the new battery - after some time I went to another region, on the highway I had a mileage of more than 4000 km, I think this is enough to charge it. However, the problem only became more frequent. I also disconnected the negative terminal for an hour or more, this did not give results. Strangely, the car asked me to calibrate only the passenger window. And as for OBD-II, there are no problems with scanning all systems and components, apparently this is a physical problem in the wiring, lock or something else.

Maybe I don't know the technical procedure that exists. I know that if you disconnect the negative terminal for a long time, the car will ask to calibrate the windows. The last time the car just calibrates only the passenger window, it's quite strange.

Once again, even though you drove that far, these alternators in our cars and NOT battery chargers, so it will never charge the battery up to full capacity, it will maintain what it has, and charge a "little bit". Our cars have a lot of electronics in them and the alternator has to deal with all of them, so charging the battery from maybe 50-60% to full, won't happen. You need to put the battery on a REAL charger and bring it to full capacity, then see how things work. When these batteries get low, the car will do weird things as I stated. You might have an issue with the BCM, (body control module). And low voltage will do that sometimes. Good luck.

Ok, I'll check how charged the battery is and charge it fully. Thanks for the advice!

You are welcome, I hope that helps.
