A/C blowing hot air
« on: 29 May 2017, 05:41 »
Hello everyone. In this fantastic weather I decided to use the a/c on my TDI for the first time to find that the a/c was blowing hot air. I decided to leave it on for a while to see if it takes time but still blowed hot air. Does anyone the best way to diagnose the issue?

Check and see if the compressor is engaging when you select the cold setting...the pulley will be getting driven by the belt but the clutched centre needs to be turning as well. One of the reasons it will fail to turn is lack of gas...they are designed that way to protect the compressor. If that turns out to be the case, a visit to a garage which can re-gas the system, is the next step...they will do a leak test at the same time (if they are any good).

Hope that helps.   :smiley:
