2012 R57 with about 80K miles. Top worked fine last summer. I have not lowered top since last summer, now both rear windows and top do not want to go down. Top will not even go back the "sunroof" section. I get the top error message
I dont hear any noise at all with rear window switch like it is even engaging. I tried the window reset, but only the fronts go up and down, nothing at all from the rear.
the only thing I have done lately is replace the rear truck switch "chrome" piece was done a few months ago, by me. nothing much with that. any suggestions on what to check or ?
It is my daughters car. I plan on getting a look at it more closely soon, but for now it is out of town. thanks

 

Not really an update. But I was getting a temp error code. So I ordered the ambient temp sensor and I am going to switch that out on reset codes to see if that may be it. I saw temp error code and thought thermostat but maybe that sensor

 

Fixed it today. It was the ambient temp sensor. For R57 you can access it in right front wheel well. It was physically broke. Put new one on and worked right away. I had to just place it behind front bumper. Could not figure how it snapped into slot
