I have a 2001 Land Rover Discovery II, It has dual comfort control, driver, passenger controls, cool air works on the drivers side but not on the passenger side, the air does come full force, but not cool...I suspect a servo motor, or a stuck flap, when I press in diagnostic test, no fault codes show up..???

The first check should be taking operating pressures. Many systems duct air thru evaperator coil which should be one even temp but with a low system charge can have cooler and warmer spots directed to one side or the other. Usually it's driver's side that suffers but with this vehicle it might have been engineered for "right" hand drive and results reversed. Begin with those pressures before taking on trying to diagnose the barbed wire mess of how or what could be at fault in ductwork sensing temps and controls, actuators and diverter doors, T

Thanks for your reply, In my limited experience with air conditioning, I never considered the pressure in the system, your answer tells me a shop is the next step.

It's not unlike a Doctor's visit. You weigh in and get your blood pressure taken and go from there. Just understand that pressures are telling of what's happening in the heat exchange operation which A/C is all about. You could do a test by hand with no tools at all and find what I expect which is a low charge. Two lines, High and Low go into the firewall - high side is triggered to evaporate (expand) which makes it cool to the touch and should be able to stay that temp for its residence time in the evaporator so the larger line out should be almost exactly the same temp if you are touching the right spots. Bet the output (larger) is warmer and it shouldn't be in yours - classic low charge. Hey - I can only guess from here. Odds are it will be found low and the reason a leak of course and then finding and fixing that is the long time fix. Just pray it isn't dash, duct and controls with a dual zone system, T
