If only cold air is blowing out of the rear vents in your 2001 Mazda MPV, it could be due to a malfunctioning blend door actuator, which controls the mix of hot and cold air. Another possibility is a low refrigerant level in the AC system, affecting its ability to produce warm air. Additionally, a blocked or malfunctioning heater core could prevent warm air from reaching the rear. It's advisable to have a professional diagnose the issue for a proper fix.

97 Mazda Millenia only blowing out hot air from air conditioner?

that usually means that you turned off the A/C on a higher degree. If it was cold in the morning and you had the A/C on 90 degrees, then turned it off, even when the A/C is off it will still blow out hot air. Vise Versa. If you had it at 65 degrees, turned it off, the air will still blow in cold.
