Had the new-fangled automatic A/C cabin temperature module fitted by my dealer a couple of weeks ago at a cost of over £600 with labour.
As far as I can tell, all the other members on here who have had it fitted are having the same problem with the "22° bug". Basically, irrespective of the temperature you have dialed in, the unit randomly but regularly switches itself back to 22°after a few minutes, thereby rendering the whole idea of an auto temp control completely useless.
In the winter when I'm well wrapped up, I will maybe set the dial to 17 or 18 degrees. No problem for a few minutes, then wallop, I get hit by a stifling blast of hot air in the face. I look down and yep, it's reset to 22°.
I have mentioned this to my Ford dealer a couple of times, but they have no idea what could be causing the problem and, when I tell them everyone else is having the same issue, they say that it must be a problem with the units and leave it at that.
TBH, if I had know (and given the cost), I would have left the manual unit in. What would you do? Ask them to put the old unit back in and refund me the £600, or wait until a fix comes out?
