There are two types of piston compressors currently in use, the opposed axial type, (also often referred to as the swash plate type), and the single row axial or wobble-plate type. Depending on design, these compressors may contain five, six, seven, or ten pistons.
With either type of piston compressor, the pumping action of the pistons draws low
For reasons we just can’t figure out the number one internet search for mobile A/C components and the number one blog post consistently read is about the function of the system’s receiver drier.

Use a digital volt ohms meter (DVOM). Set your meter to DC volts. With the engine off, hook the negative lead from the meter to the negative post of the battery.
A vehicle has many electrical circuits. For an electrical component to function properly, the electricity must return to the source through the ground side of the circuit. Ground paths are usually metal conductors such as wires or the vehicle frame, engine or body.
One way to check for proper coolant circulation is to check the upper and lower radiator hoses. The upper radiator hose should be hot, around 190–200 °F. (The safest and…
