Weird question here! I have a 2018 q7 with 85k miles. Last year I noticed when I went through an automatic car was that the console vents stopped blowing cold air and hot air was forced out of the defrost vent. Rear vents worked fine. After a day the ac worked perfectly fine. It happened again and since then I have turned off the ac when going through the car wash. This seems to solve the issue. 3 days ago I forgot to turn off the ac and since the center vents are working intermittently. It has to be tied to the car wash because I have had zero issues otherwise. Has anyone seen this?
