It is very inexpensive to replace a serpentine belt, fan belt, AC belt, or power steering belt whether it’s broken or loose. The replacement cost of a drive belt is only going to be between $100 and $200 in most cases. The belt itself will cost between $30 and $90 while the labor costs will probably be between $150 and $200. Air vents blowing hot air when set for cold. Hello everyone. I am having a small but annoying issue with my 540. Basically the air vents will blow hot air even when the temp is set to the lowest setting. The problem is much more pronounced from the passenger side vents than the driver's side, thankfully. Even when running the AC full blast, the When the fans are faulty, the airflow is not going to happen, and you are not going to get the cool air. Do a visual inspection for this one, too, and see if the cooling fan is not broken. In case it is, you need to make a replacement for the same.

X5 e 53 2001 4.4. Replaced above heater valve with bmw Oem. Replaced ac electric fan. I get cold ac from dashboard vents, but I can feel some hot air seeping through. Ac is not the problem. Very hot air only on feet and windshield when zone selected with ac on. Dashboard, feet and windshield flapper valves work correctly.
NEED HELP FAULT CODE E723. 2007 BMW X5 . A/C not blowing cold. A decent BMW diagnostic scan tool will tell you codes in words much clearer than the original post above.

2) Low coolant level. Check your coolant level by the floating stick gauge when the car is cold. Air pockets will naturally gravitate to the expansion tank, and will generally only move to other areas of the cooling system if the level in the tank is very low. 3) Sticking heater valve.
Hey, just had this problem. Warm air on the driver's side and cool on the passenger side. Freaked out from all the posts about an evaporator leak and having to take apart the dashboard. Repair going to be $2,000 to $3,000. Had not had the A/C serviced for a while. They did a complete evac and recharge. Cold as ice now! r4r5o.
