Hello, which may be the reason that the windows, electric mirrors, interior lighting are not working, and I cannot code the central locking. The car is a Golf IV 1.6 2000 year, the problem appeared about two weeks ago at a temperature of -25 degrees. I wanted to open the car with the remote control and couldn't, I opened it with the key, but only the driver's door opened. As I was able to enter it, I wanted to start it, as soon as I inserted the key, an alarm was triggered that I could not turn off by disconnecting the battery. I tried to pull the small fuses on the left, but nothing helped. The alarm turned itself off after about 10 minutes. From that moment on, I couldn't close the car, the mirrors and windows were still working normally. Only the interior lighting was not shining when I opened the driver's door, when I opened the passenger or removed the key from the ignition switch it lit up normally. I read that it could be guilty of broken cables or the lock itself, in which there is a micro switch or something. The cables were ok, so I bought and replaced the entire lock, the lamp began to light, the buzzer that the lights did not turn off also buzzed. I put together the whole door, closed the car with the key, opened it and another problem arose, because immediately after opening the car, both windows completely open. The only way to close them is to open the door, insert the key in the lock and hold it as if the car was locked with the key and the windows closed. I can't code the central lock, I've already replaced the remote control batteries and nothing. Someone wrote somewhere to check if there was electricity to this lamp so I took the electric test tube and checked it. Any advice on what to do about it ???? Thank you in advance for all the answers
