Help electric problems

[kommandantkarl]

My 2013 BMW 135i is giving me the following problems:
-When setting the light to automatic flickers.
-Reverse lights do not work. Already replaced the bulbs and checked the fuses.
-when pressing the button for the window to go up, it goes halfway and goes down. It works after 2 attempts.
- The garage button to open the garage does not work sometimes.

The battery was replaced last year. Two of the problems preceded the battery replacement.

Any ideas?
Thank you

I'm a member and if I have an issue I can go in to their technical editor and get an expert answer back usually within 24 hrs. Also I now know of at least 6 indy garages that know BMWs very well in my small city here.

85% of all weird electrical issues are caused by loose and/or dirty connections.
