I learned something new that I should pass along to ALL.When I was aligning the roof bike rack on my 2022 V90 B6, I was standing in the driver's door ledge. When I finished I noticed that the front seat was inclined all the way. The toe of my shoe had been against the switch. When I went to lean it forward, it would not move. But, the bottom of the seat could be raised, lowered, moved forward, and backwards.I jerked around on the back for a bit thinking it may be jammed, and then, for some unknown reason (the Gods are watching over me), leaned over and checked the passenger seat. It too had the same issue with the back, but the rest of the functions worked.I started pulling fuses and checking them. I then noticed that when I pulled the fuse for the driver's seat, and then replaced it, it had no functions. The bottom did not work. The massage (no, it came with the used car. I would never pay for .....) would not work. Humm. Then I did the same for the passenger seat and it did the same. When you pull a fuse, even if you replace it, the seats lost functions.Then it came to me: COMPUTERS.I disconnected the negative lead on the main battery for 15 minutes. Reconnected it, and let the car sit for 5 minutes while it went through a reboot.Everything now works. It is like the IT Tech. Did you reboot your laptop? Try that first.
