So my e53 2002 x5 was not blowing cold air that much. and it was tested for leaks and there were no leaks found. So i recharged the system with r134A GAS.
and its weird how the center right vent blows hot air and passenger feet area is hot. while pasenger right vent is semi cold. the drivers side is perfect with ice cold ac. So i think this has to do with the cooling zones. this vehicle has the tri-climate. passenger, driver, and rear zones. and i also tried moving the knob to 3 blue. so im stuck wondering why are those vents always hot? Perhaps a clogged vent or it doesnt switch the settings??? if someone had this problem or has any tips please respond below thank you
