CMAX Power Window Failure
Summary of the thread
After swapping the battery in a 2015 Ford CMAX diesel, the power windows stopped functioning, despite the fuses being intact. The issue appears to be related to a failed window regulator initialization, as indicated by a code reader. A potential solution involves re-initializing the window regulators using a scan tool, as basic reset attempts were unsuccessful. If the problem persists, it may require professional intervention to recode the Body Control Module (BCM).

Yeah, I tried holding the button up and down, for like a minute each way. Also disconnected the battery again for a while. Still nothing.

Blast, that's what I was hoping it would be. When mine did that, I messed around with it for ages and then caved and took it to a workshop. There is a procedure with scan tools to re-initialize the regulators, but if the basic reset isn't working you may have lost the coding in the BCM. You might need to get it scanned properly and coded up - they hit me for 290€.

Ugh, that's what I was afraid of. Sounds like a trip to the shop is in my future. I'll post what happens once they've taken my money. Window regulator, what a pain!

That sucks! I had something similar on my Ford Focus after disconnecting the battery. The window motors sometimes need a reset. Did you try holding the button down for 10 seconds?
