Any one have a wiring diagram for the power windows they can share? I have a driver side rear window not rolling down. I have tested the motor it works, sent FRM to bimmerscan it’s good, giving 9CDA and 9CDB codes which refer to that rear window, I’m thinking it’s a bad wire somewhere, thanks for the help

 

What year R57?

I did a quick look for rear power-window circuit diagrams in the Bentley manual and could not find any. But I'll keep looking.

Is your scan tool able to view data streams/live data and/or actuation tests/active tests for the power windows? These tests may provide valuable diagnostic information. For example, the images below show the relevant features found a Launch scan tool connected to my 2012 base-model R56.

 

thanks its a 2012, I do have ISTA but have recently experienced issues connecting it to the mini

 

I found this power window circuit diagram for the 2012 Countryman. Maybe its the same as or similar to your 2012 R57.

 

Both codes seem to indicate an issue with the power window receiving constant voltage from terminals 30A and 30B. You may want to check whether the FRM receives battery voltage from both fuse F4 and fuse F8 in the JBE.

 

wow, you got it! It was F10 it was just completely missing. This was my daughter’s car and a shop worked on it last summer trying to diagnose an electrical issue related to a fuel pump, they likely pulled it and never put it back.

 

Nice work!

I think the missing fuse is actually F8:

 

it was F10, right above the 15A fuse

 

Good to know that the R57 JBE fuses are organized differently than is shown in the Bentley manual.
