Re: Air conditioning only blows at feet and defrost Chevy Equinox 2013
There is only ONE Blend Door. It routes or allows EITHER HOT air from the heater core OR COLD AIR from the AC coil to flow through the HVAC system.
There is a MODE DOOR that is just above the BLEND DOOR a bit, and it controls and routes air either to the Defrost/Floor vents OR to the UPPER Front Dash vents above the radio.
So it sounds more like your Mode Door. The Mode Door actuator is on the Left side of the Center Control Stack and the Blend Door actuator is on the Right side.
Do some searches here using the SEARCH BOX upper right for Mode Door. .. .. Lots of info here if you do the leg work. . . complete with pictures and hints on how to diagnose and repair.
