i just recently purchased a 2015 Ford Escape and the ac is blowing warm air. i checked the pressure and its 40pis low and the high is 140psi. the ac compressor clutch is engaged and the low- and high-pressure switches seem to be reading good. my questions is what could be causing the ac to still be blowing warm air ant thoughts. any help would be greatly appreciated.
