My air con stopped putting out cold air. I called in the mobile air con guy who tested the system and said it was all fine. He thought it was an electrical problem. He pulled off the connector to the air com pump. Then all the fans stopped working also the temp gauge. The display says "Check Air con connector" He told me to take it to get it checked by Lexus and disappeared rather rapidly. Can anyone tell me whether discharging the electrical system and resetting it would fix this or does anyone know what I can try before going to Lexus (££££££££). Model is LS430 on an X plate.
