I never really liked using the a/c. and when i do it's usually when its extremely hawt. Ford recommends using max a/c, supposedly it's more fuel efficient (from what i read in the manual). However, when it goes on. the engine feels like it wants to kill itself. and shifting is a pain the butt. can't even release the clutch without that feeling of popping in to the gear. whats worse is the ac doesnt get farther than 4 inches out of the vent. this can't be a problem i know. the car is brand new, but does anyone elses car act stupid when the a/c is on?
