This may seem an odd question - but the indicating light in the A/C button is suppossed to stay illuminated when the A/C is on - right? I ask because mine doesn't. I only noticed today after I got in the car mid afternoon with the car having been in the sun for a few hours. The A/C didn't seem to be getting very cold, although it was cooling slightly. Started to check the settings and found this problem. The light illuminates as I press the button, but goes out as soon as I release it. In this weather would also exepct it to be on when I select Auto. I've booked it into the dealer next week anyway.
