The main reasons for your Volkswagen Golf Mk5's air conditioning not functioning properly are likely blown fuses or relays, a refrigerant leak, or a faulty AC compressor. The simplest to address is checking the fuses, which can be found in the internal and external fuse panels indicated in the owner's manual. Look for any fuses related to the climate control system and inspect them. To test the relay, identify the one that controls the AC and listen for an audible click when you attempt to switch the system on or off. If the fuses and relays appear to be in good condition, check the R134-a refrigerant level, as low refrigerant may cause the air to blow but not be cold. Finally, if necessary, have a mechanic inspect the AC compressor.
A faulty AC relay, compressor, or blower motor can lead to the air conditioning system failing in the Volkswagen MK5.
