Intermittent A/C heat only problem

Hi all,

I've got a 06 Z4MC and last night the A/C start acting up and will only blow hot air (not ambient, but actually hot air). Not matter what setting I tried with on/off auto, A/C, circulation, max, the hot/cold dial, it will only blow hot air.

I even tried turning the auto and A/C off and get it to act as a fan only and blow air from outside, it will still be blowing very hot air, even though it was nice and cool at 25C outside. The outside temp display looks to be working ok with a display of 25C.

However this morning the A/C was back to its usual self again, has anyone had this problem before with the famous BMW reliability?

Thanks! :headbang:
