It would be nice if the Focus had a way to disable it.
Hi, actually todays modern A/C make little difference to your engine power or the mpg especially on a 2 litre engne. The compressors are smaller and aren't on all of the time. I leave mine on auto all year round as it makes better sense for the maintenance of the A/C components...
