Climate Zones. ac recharge- e53
 

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

Does your aux fan come on at all? I'm having a similar problem, my aux fan doesn't work so I'm not getting ice cold air, except on the driver side.

I checked the fan. It comes on slowly and turns on and off when needed. The way it works is the drivers zone gets all the air than it splits to passenger than to rear. That's why you have the most speed of air coming out from the drivers side

same issues here, driver side 2 vents blow fairly cool air. But the pass 2 do not. Def. not cold enough air to keep the windows up on a hot day however.

Recharge it and drive around with the settings on max. It could be the old r134a gas

sounds like you may have a stuck heather valve.Try to give it a gentle tap while someone switches from hot to cold from inside the cabin and see if that cures your AC problem.The valve DO get stuck from time to time i have seen it on my 5 series.When i got it, it was blowing full on hot air even with the ac on on max.Taping on the valve cured it:)
Hope that helps

Thanks for the info. Please correct me if I'm wrong.
So I will open up the vent. Tap the valve inside
While someone switches the knob?

The valve is lockated in the engine compartment next to the driver side suspension tower I believe.Start the engine, have someone sit in the car switching from ac to heating while you tap on the valve with something(I used the handle of my hammer).Be gentle!!once you go tru switching and taping couple of times, switch to ac again and check to see if you get cold air from all vents.That helped me.Hope it helps you to.

Refrigerant does not go bad or get old.

Are you out of your mind?! ^
Than why do cars need a recharge. If it didn't leak out? Can you explain why they sell refrigerant kits at every store. So why does the ac
Stop cooling?
