Hi my aircon stopped working so i got it re-gased, it still doesn't work, the light comes on next to the ac button but the air is not any colder than normal cold air. person who re-gassed it said it may need to have the computer reprogrammed as he doesn't know why it isn't working, still took my money though!!!! does anyone know if this is true or is he just bullsh***ing me. any advice would be appreciated thanks
