Only driver side buttons don't work to roll down windows. And seat memory for both passenger seat and driver side doesn't work. I got these codes. I reased them and they came back. All fuses connected to them are all good. What can I do to fix it

Did all three conditions happen at once, or have they been failing over time?
Initial guesstimate is to check out your wiring a bit: https://www.underhoodservice.com/bmw-k-can-wiring-shorted-in-various-locations/

I got better liner for around the buttons so I unplugged my buttons to roll down the window and it worked for a day then it all went out

One other check is to reset the LIN bus itself. Clear codes, Disconnect the battery for a few minutes, then see if codes return.

I reset the lin bus with the obd2

The lights for the buttons aren't even on that's why I thought it was a fuse. But I checked all the fuses for the windows and seat memory and they're good

I’d focus on the door harness wiring as that sounds like your root cause. Maybe unplug the door buttons, clear the codes and reset LIN, then confirm that your memory seats are ok and you have only rhe expected code for the door buttons.
