Good progress today. My neighbor charged up the AC with 134a. He put the vacuum on it for about 45 minutes and the system held vacuum. The 134a went in OK and the AC was blowing 55 to 60 degree air which is not great but I'll take it. The weather here in Houston is mild right now so it'll be a few weeks before we have a 95 degree stress test. The real test is if the thing keeps the refrigerant in overnight
Curious, was this 55-60 at idle only? I know when i start AC its roughly around that temp and when i drive some temp drops really nice around 35-40
Awesome video! Thanks for posting.

It could be that the temp will drop when the truck is moving. If my AC system is under-performing, which it may be, I don't know what's causing it. The whole thing is new to me and I have no previous knowledge about it, what was replaced, and how well it worked. It does have a new dryer and blower motor, but those are the only obviously new parts I can see.The good news is that the system held its charge over night and was blowing cold air this morning. For now I will leave it as-is. As Houston starts to see regular temps in the 80's and 90's, I will get a better test of the system's performance. I'll dig up my AC vent thermometer so I can get a consistent reading on the air temp output.
The Blazers and Suburbans have an inner panel to do the same thing.
I purchased one when I restored a K5
Fit perfectly, in the K5. The gauges are electric although oil pressure was mechanical through 77
