I was washing my GLC and had the key fob in my pocket. I leaned against the seat and I think I pressed the "unlock" button for a while. All the windows went down a inch or so. This might be what happened.
Went in a store came out and all my windows were open and the sunroof too???? Just had a MBUX software update a couple of days ago.Hi I cam out to my GLC today to find all 4 windows slightly open - about 3-4cm. I hadn't left it like that last night. Does anyone know why?
