I’ve searched high and low to see if anyone has had similar problems that I’m experiencing, but no dice. I’m hoping maybe yall can point me in the right direction.

About 2 years ago my LX started not remembering the last temperature and fan setting that it was at when I turned it off. After a few months I started investigating what might be the causes, and a common theme is the recirc door being broken, well I had not had my filter replaced and when tested it seems to work fine. I’ve replaced the filter twice and checked the door function and it appears to still be working correctly. I was content to live with this annoyance, but earlier this year the passenger side stopped blowing hot air. Not long after that the driver face vents stopped blowing as well. I’ve used techstream to reset the servos multiple times with no change. I just pulled the codes again today and they are B1441, B1443, B1445, & B1448. I’m assuming I’ll need to replace a servo the passenger side, but I wanted to try to get some feedback before throwing parts at the problem.
