'01 V70 X/C Window Issue

[benpineapple]

Hello! My wife's V70 X/C has had a few odd electrical gremlins I've been trying to fix. One of them relates to the Driver's Side window. When we got the car, the window motor was obviously failing, so I replaced it with a decent used one that I confirmed worked before installing it. Identical part numbers for the old and new one. I also replaced the DS master window switch with a used one I tested, and it works (old switch was cracked and gross).

Issue: DS window only functions when the driver's side door is open, regardless of whether the car is on or if the key is in pos 2. All other windows will function with the DS open or closed. Maybe this is related to the open door switch somehow? No idea what the solution is here, super odd issue for me. Let me know if you have questions or need more information.
