Can you tell me where the Orifice Tube is located on my 1987 Chevy Caprice?

To properly evaluate your AC system you need the high and low readings. You also have to factor in the ambient temperature. Look up a chart on the web.

I had the temps and Gage readings and the high and low side read correct, but the inside wasn't blowing cold as it should be. Im not sure of what the inside temp was reading but its wasnt cold at all. Would the Orifice Tube have something to do with this.

First try cleaning A.C condenser coil with garden hose and nozzle maybe clogged with dirt and bugs causing little to almost no air flow across the coils. If radiator sets in front of condenser clean it also so that you can get good air flow to condenser.
