My car will not switch vents to defrost. I ran the diagnostic by holding down auto and air circulation button and I have no codes. I was thinking it was the Air Servo outlet motor but now I’m not so sure after I took the top of the dash off and watched the gear move as I pushed the button switching the vents. Has any had this issue and might have a fix or some guidance. Having no code for a bad output servo has really thrown me.
