My 2020 FPace blows cold air out ac vent and floor until car warms. Another time, works good but when idling, cold air came our of heater vents.
I have had two other Jags, Lexus and Caddy and never have I had it to blow cold air our of the ac vents like the ac is on before car heated up. They have always stayed off until car is heated which doesn't take long. I mean you are freezing your buns off while all that cold air is blowing out on you. And I do have everything or auto. Just was curious before I take my car in to the dealer what could be the problem. Could that be a thermostat problem?So cold air coming out of the vents before the car warms up is normal. The engine needs to be warm for the heater to produce warm air. When Idling is not normal if the car is warmed up completely. The only exception to that might be if you car is stopped and you Auto/Start Stop kicks in I'm guessing the hot air could get a little cooler, but should still be warm. I am commenting there without specific experience since I have my Auto start/stop disabled.
