Look for a blue plastic valve or cap on valve on one of the lines near comp-that is low pressure side. High is red.
It is on the top of the ac compressor.It is on the top of the ac compressor.

where is the low pressure port for the a/c -- 93 ford ranger 4.0L -- super-cab
Trace the lines from the compressor. Probably toward the firewall you will find the low pressure port made to a sliver pipe.
The low side AC port on a 1993 Dodge Dynasty is located on the passenger side of the engine compartment. Specifically, you can find it on the larger of the two AC lines, which typically runs between the compressor and the evaporator. The port is often covered by a plastic cap, which may be labeled for easy identification. Always ensure the engine is off and the AC system is de-pressurized before attempting any service.
On a 1993 Buick Skylark, the low-pressure AC service port is typically located on the larger diameter aluminum refrigerant line, which runs from the evaporator to the compressor. You can find it near the front of the engine compartment, often close to the firewall. The port is usually capped with a plastic or metal cap, which may be marked with "L" for low pressure. Always ensure the engine is off and the AC system is not pressurized before attempting to access the port.
If you are facing the engine from the front, look on the right side and down probably about 9 inches or so. The low pressure port is on the larger of the two hoses that go into your AC. This is the only AC hose on the right side.
Refrigerant is added through the low side service port. That is the smaller of the two fittings on the ac lines.
