1993 Aerostar A/C question

[Junky1991]

Hello, just picked up my Van yesterday, I love Aerostars BTW and a question I have is that my ac is not blowing out cold air and upon looking in the enigne compartment noticed that my system was retrofitted with R-134a. Now I know they sell that stuff at walmart to recharge the system but does anyone have any experience using this stuff. I saw one kit yesterday when I was buyin stuff and it was like 20.00 had a guage on it and everything. Any help would be great....Long live Aerostars!!!!!!!!!

It works great, at least it did for me, Just plug it in the low pressure side, and the gauge will show how much you need, I think it shows by colors.

Yea, it showed 45 psi but I dont think the compressor is on, didnt seem to bog down the system and was not getting cooler, o well its about fall time, my windows roll down.
