A fellow forum member stopped over today. After 3 seasons of ice cold A/C on his 1996 B4 TDI even up to using it last season, it is blowing warm air this season. Upon putting the guages on we found his low side to be abnormally high @ 50PSI for the ambient temp (72F) outside and the high side to be low at 120PSI. We added a can and saw no low side change, and high went to around 120PSI. Still warm air. I seemed to recall having a high, low side pressure can be cause by blocked orifice tube. We pulled the Bentley and found the orifice valve was a block right before the lines went in the firewall. Can these cause this issue? Any input or direction we can send him would be helpful…
