Locking issue and passenger rear window doesn’t come down

[Abraar]

Hi guys! 
 

I’ve just got my hands on a BMW 1 Series 120D and noticed that the driver door doesn’t unlock/lock with the fob. 
 

Also, the back left passenger door lock when I try lock/unlock jumps up and down a few times and takes a few times for it to get unlocked. 
 

Last issue is the back right passenger window doesn’t come down from either of the switches. 
 

Has anyone faced these issues before, any help would be great 🙂

Welcome to the Forum

First do you have a second key to try? If that makes no difference then you clearly have faulty components a Scan with a BMW capable Diagnostic would give more accurate information. Simple things first swap the rear door window switch with the other side (it will plug in but wont fit in the door don't force it) if the window works you know it's the switch if not it seems you need to get a new lift mechanism. Your description would indicate a new Actuator needs fitting, last the Drivers door actuator needs testing as does the switch module.

As said the help of a BMW specialist at least with the proper Diagnostic's would save a lot of time if you can't do it yourself
