hey guys,my vl calais today had all windows working fine i drove it for 10 mins had the windows down. i turned it off then came back and went to drive it and rear passenger didnt want to go up (both switches wont work) then again happened to my drivers window they were all working fine this morning... so no idea what has happened (faulty switch maybe)? pretty rare if all the motors shat them selves all at once. has anyone had this happen to them before any any idea to what may be the problem
