Hi Scotty! I hope your move to Tennessee has gone well so far. Houston, Texas misses you for sure. As a former Houstonite, you know my desperate need for cold air in my vehicle. Recently, I have taken on my childhood van as a "fun" project. In doing so, I initially found a vacuum issue since the a/c would move to defrost upon acceleration. After scouring many videos, I identified the vacuum lines causing this issue and installed a reservoir and check valve. I have plenty of air flow now but I am not getting the cold air I am looking for (test thermometer showing 80 degrees). I have tried to add a touch more Freon but didn't want to add too much. While reading the gauges, I am seeing 50PSI on the low and 200PSI on the high. This is at 95 degrees with your normal Spring/Summer humidity here in Houston. My compressor does cycle on an off but not short cycling. I can't see my vacuum changes causing this issue (but I could be wrong). Could this possibly be a blend door actuator issue, clogged orifice tube, or just a faulty compressor? It might be worth mentioning that I have rear air control too. Both front and rear do have some condensation drips.

As old as that thing is it could be a zillion things but I would advise evacuating the system out with a vacuum pump then filling it with a factory load by weight of refrigerant. If it's still in blow cold enough for my experience with those normally means the compressor is just worn
Hello! Just wanted to follow up and let you know that I followed your instructions and vacuumed the Freon and replaced the orifice tube and drier. All is cold now. However, it's not great at idle like traffic or lights. I'm sure you remember both from Houston. The clutch fan works but would you recommend installing a aux cooling fan with a manual switch for long idle situations?
