CMAX Power Window Failure

My 2015 Ford CMAX diesel, with 230k km, has a weird problem. I swapped the battery, and now the power windows are dead. Fuses are good. The code reader says the window regulator initialization failed. Any ideas?

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).

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?

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!
