Took her to the shop had it evacuated and recharged. They put in 36 ounces of r134. Blowing 38° sitting at 1500 rpm and 36° going down the road.

It's been quite a while since I worked on that particular model-year vehicle, but I seem to recall that the compressor and manifold have shallow circular reliefs cut into their respective flanges, into which the seals fit. Then the center bolt is tightened to partially compress the seals to such an ...

Another question….
When a system loses it’s complete charge how do we determine how much oil is left in the system and how much needs to be added back?

If I change only the accumulator how much oil should I add to it?

Many shops will do a charge of refrigerant and UV dye then have you come back in a week so they can find the leak with UV light. Could this be what that shop intended?
Probably

If a new accumulator was installed after the car sat for 2 years and that shop then charged it, if mine I would not ...

I explained all this to the guy doing the work and don’t understand why ...

I took the truck and had the ac serviced Aug 4, and I asked to keep track of the operating pressures while charging the system, but he did not do that for whatever reason. Why is it so hard to get anything done the way you want it today?

Center vent temperature reads 41°F at an ambient of ...

I did not pay attention to the readings, I was only going by amount of refrigerant.

It could’ve taken the full amount, but I wanted to make sure I didn’t put too much in. That temp is with the truck sitting in the drive.

I charged it only the low-side service port, cans upright for refrigerant gas, engine idling, windows open, system set to Max Cool, temperature set on full cold ...
