this car is my wife's daily driver, I don't drive it much. several months ago I drove it and noticed that the actuator motor was running all the time and it was making a clicking noise. I have no idea how long ago this issue started or why. I tried using the power fold switch and it wouldn't close, remained where it was, but after operating the switch the actuator motor stopped moving and making the clicking noise. I attempted to "gently" open/close the mirror manually, which I was able to do. I assumed that some part within the actuator broke, and eventually I'd have to replace.
The mirror tilt and adjustment function still works fine, but not as smooth as it used to be. the issue is the power fold feature.
Fast forward a month or so, and at some point the mirror lost the ability to stay in a fixed, open position. It now kind of flops around now, which is really annoying while driving.
