ALL FOUR WINDOWS STOPPED FUNCTIONING AT ONCE. RESEARCHED THIS PROBLEM AND IT IS EXTREMELY COMMON. THIS IS A MAJOR SAFETY PROBLEM IN CASE WINDOWS ARE NEEDED TO ESCAPE FROM VEHICLE DUE TO ACCIDENT. THE TEMPERATURE OF VEHICLE CAN ALSO EXCEED SAFE DEGREE DUE TO WINDOWS NOT OPENING. NO WARNING WAS GIVEN BEFORE ALL WINDOWS CEASED TO FUNCTION. STARTED VEHICLE AND WINDOWS WOULD NOT WORK FROM ANY CONTROL. HAD TO TAKE MOTHER TO DOCTOR FOR HEAT EXHAUSTION FROM EXCESSIVE TEMPERATURES BUILDING UP IN CAR.
