Update. Vacumned it down, then charged it, about 80 degrees with 40 on low side and 200 on high. Thought it might be right, blowing cold at 40 degrees out vent. So next morning drove 30 miles freezing me, about 78 outside. After golf it was 92 and very humid, turned on AC, it worked for about 9 minutes then blowed hot air, btw the compressor never shuts off. Get out on highway at 55-60 it stays blowing cold till I slow down or stop, have to turn off and on to get working again. So the question, expansion valve or high-low pressure switch? Remember the compressor does not turn off like I’m thinking it should cycle every so often.?
That HF suck pump works great for $15.
