AC Fault

The AC fault light (the opened book with the exclamation point) came on last night in my Rover. I looked this up in the owners manual and it just told me to head over to the dealer. Any ideas on what is triggering this fault? Has anyone else had it triggered? Should I rush over to my dealer or can I drive with it in its fault condition? Thanks for any help!

I am having this same problem I know it was a year ago but did you find out what the issue was?

need t-4 to find out probably best case senerio heater core temp senser maybe a cooked relay in master panel or worst a blend door motor. Good news the light goes out as soon as its fixed check the relays first any sign of a barbeque burt or brown buy a new one in the master relay panel in the engine bay

By summer when things get hot you will want to have the dealer check it out cause you will probably be getting a little warm.

mine is the same, but i think i figured mine out.. the drivers side will not blow hot air and the passengers will..

that's exactly what mine is doing...dealer says replace ATC Control Unit and left and center acentuater doors...how about you?
