Sometimes My A/C stops blowing when I adjust the control up/down

Took it to a shop where they suggest changing the blower motor and I did that.

Notice the same problem after a while but this time I noticed that the SOS inoperative warning sign also flashes whenever problem occurs.

I do have a “lane assist inoperative” sign on and this has been there way longer before the A/C issue started.

Hello and welcome to 2CarPros. There is a bulletin for your concern if the blower motor is shutting off. See images below for part numbers to have your mechanic repair the connector. Unfortunately the bulletin does not show the actual repair procedure. Have them look at it and let us know if it works.
