help

Hello friends, I have been living in Eskişehir for a month, I am a user of 2000 model 406 2.0 hdı sv. I have several problems, I would be glad if you help. the rearview mirror is dimmed but it is not working. But there are 6 cables coming from the ceiling, if I think they are all idle, it has a rain sensor but it doesn't work. These 6 cables are not in the socket. Are there any friends or people who have a photo of this part? There is a squeak when the steering wheel turns slowly. Finally, I asked if the brake pedal and the accelerator are at the same level of clutch above, because it is normal because the brake is down, so I asked how the pedal status of your vehicles is. please give information

For the rain sensor, you should take aoto to the arm, pour water on the windshield.
