Hello People.

I have a question regarding the passanger door (left hand side, UK car). I have changed front left door in my car - Volvo S40. After changing the door, indicator on the mirror and mirror adjustment works, but the car won't lock. I have replaced the door control unit with the one from the previous door (the one that was on the car before) and car locks but the indicator on the mirror and mirror adjustment doesn't. My question is, how to get the indicator and mirror adjusting working as well as the lock? I have two door control units, but I dont know what to do with it. I have included pictures of the door control units, the one Im holding comes from the old door, the one fitted is from the new door I fitted into car. Thank you for any help.

Regards

 

Doesnt these electronic parts needs to be programmed to the car by the dealer?
