Agreed. While my shops have R134R and 1234YF equipment, I didn't think to check it when the car was in Michigan. I'll just suggest she have the system evacuated and re-filled correctly. (She is in Denver.)
I just wondered if this was a common/known problem due to a faulty sensor or setting.
Please consider this thread closed unless I open it again if a re-charge doesn't fix it.
Thanks.
