Question about AC Cars & Trucks
The dealer will not give out the fuse diagram for the 2011. they claim it is a VW policy? What kind of business is this? My AC is blowing hot air and I have Freon, so I am thinking it is the fuse
Do you have your owners manual? If you do, there should be some info available for the location of the fuse box and a description and ratings of the fuses and relays.
Sometimes the fuse box cover will also provide this information.
The first place to start your trouble shooting is to look for a tell tale dash indicator alert for potential fault codes.
Does your A/C compressor come on when you select A/C?
How do you know you have adequate A/C coolant pressure?
Have you checked for a broken or missing belt? If your vehicle uses
multiple belts instead of a serpentine belt (which drives all of the accessories.)

SOURCE: 99 STS AC is blowing hot air
I had the same problem but it was blowing hot air on the passenger side of the car. I assume you have the dual zone controls that I have as well. The problem is most likely the damper that controls the flow of hot and cold air into the car. The motorized component of the damper is most likely not working and its stuck in the hot air position.
I had mine replaced by a repair shop so I cant tell you how to replace it but it may be something that you can do if you have the time and patience to work on it.

you need to have it diagnosed by a professional. These are complicated systems even to a trained tech. You may be over or under charged, have a clogged expansion valve, have a leak or many other issues. This model has a rcv refrigerant control valve inside the compressor which regulates the pressure of the compressor. If you notice the compressor never shuts off like conventional auto a/c's do the only time the clutch works is when you turn it on or off. Can be complicated.

You may not be full of refrigerant... There is a low pressure switch that prevents the AC from actuating the clutch, and the reason is: IF there is not enough refrigerant, you will not be able to move oil through the system and you will have major damage...so no engauge...
Get the system checked, most likely there is a leak somewhere..
