How do you know it has the right amount of refrigerant? This is not something the average person can determine.

 

Are we're talking about your '86 wagon here or your '96 OBW?

96 obw, The 86 had to goto its final resting place Harrys upull in Hazleton. I'm not the average person I have been working on cars for 35 years now but I don't mess with A/C much. I have access to gages from a Friend that works at a shop. The gage shows the the right amount. Thanks for the link unibrook! It has no leaks we checked with the die you put in it. The line from the compresser to the cab does not get cold and the one from the condenser gets super hot.

Still sounds low, if the high pressure side isn't getting cold enough. Maybe another set of gauges would confirm the correect pressure.

What is the "right amount" Also what is the ambiant air temperiture?

 

Always give us the exact data points when we are trying to help diagnose an issue. What you may think is the "right amount" may be an important clue to the problem.

 

Also did you read the pressures after 10 minutes of the AC running for it to normalize? We need both the high pressure and low pressure numbers.

I got it working. It was the plug on the pipe up near the fire wall before it goes into the cab. It was loose and dirty. After using it on a 50 mile trip mostly up hill with the cruse on I will just roll my windows down because it sucked my gas.
