Air Con Issues in BMW X5 2002

Mid last Summer I had an issue with vapour (Odourless and Colourless) coming through the left air vents. It was still cold though. I was told this was related to the fact that I live in a humid environment. However I had lived here quite a while and never saw this before.

Recently when I switch on the air con in AUTO mode the fan speed goes to 3/4 of full speed and simply stays there with the air coming through not particularly cold and no more vapour. The other thing I've noticed in association with this is that the green light on the AUTO switch remains on. Before I distinctly remember being able to select this mode off and armed.

Could the vapour through the vents have been a precursor to this failure?

Does anyone have any ideas about what is at fault, could it be the AC control panel or is it something related to the AC system itself?

Change your temperature setting to affect fan speed and on off mode. The Vapor is a problem on particularly humid days and effects Mercedes as well this too is affected by the temperature setting.

Why does a smoke pick up steam?


Because gasoline has water in it at molecular level. When it burns under pressure, the water turns to steam. In summer you can't see it, but in winter, it shows as water vapour in cold air and drips as water from the exhaust as it condenses against cold metal.

2008 Jeep Liberty-My heater was barely warm-blowing fine tho. Was told I had a plugged heater core and needed a new one. Had a new heater core put in and then my air conditioner stopped blowing cold air....


I woild be checking the vent controls as if the ac is working and the core was blocked then the air would be cool when the heat was selected but not changing Fixing the heater has resulted in a /c not being good enough to cool the air if the vent is not properly selecting. The point is that if the vent selection is not working properly (vacuum hoses) then the 2 faults will be related.

Cold air blows from the left side. Heat will not come from the left side of vents. Right side works fine. It did this last winter, but suddenly stated working. No problem with A/C. during summer.


sounds like a bad switch. like the switch to change to defrost or on your feet ect. they should be pretty cheap if you look at a junk yard or ebay

How to troubleshoot the electrical air conditioning system 2000 GMC Yukon Denali. I put in new resistor, relay and dealer blower motor and it still doesn't do anything. Air conditioning control switch...


The compressor on the air conditioner in my 2000 GMC Yukon XL went out last summer. Had it and the whole line replaced at a local air conditioning shop last fall. Used it little before cold weather. Warm weather this spring and no cold air. We could hear the compressor trying to kick in. The shop told us that the control console was bad and had to be replaced. They told us the part was on back order and did not know if they would be abel to get one any time soon. We took the Yukon into the local GM dealership. They told us that the high side fitting was bad and that the freon was very low and that they would have to deal with that first to check the system. Called back to the air conditioning shop and they said they had a console come in and they would put it in and check the high side fitting. I now have cold air and questions. Bought Yukon in 2005 used, had always had problem of not switching to cold air once the heater has been used. We were told changing the console should fix that. It has not changed. I feel like the console angle was a scam, that the system was just low on freon. Each shop was blaming the other for trying to scam me. And what can fix the heat to cold issue? If anyone has answers I would sure appreciate the knowledge.

I charged my ac last summer, worked great. This summer the 2 vents on the passenger side work great, very cold. The 2 vents on the drivers side blow air but not cold, just like the ac is not on?


One of your Actuators inside the dash that control the A/C Heat doors/ Baffles that open or close, to either give you hot or cold air has failed. Find and replace the failed Actuator and it should work fine.

AC/heater vent only blow out hot air


that switch controls a vacuum operated door that lets a/c or heat thru.when accelerating,the vacuum in the engine changes so it sound like a vacuum issue.take apart the center stack and there is a vacuum actuator in there connected to the flap door .i have seen those have issues with the metal tab broken away from the plastic that moves it.is the a/c piping cold under the hood where it goes into the heater a/c assembly?the compressor should be cycling on and off and the pressure tested.

Cabin temperature issue


The car could be low on coolant. I would check that first and if its full then explore a vacuum leak.
