Prostar AC compressor

[Fixmytruck123]

Does your system still have Freon in it, if clutch got hot enough may have damaged seal and lost Freon. Unplug compressor and supply 12volts to it and see if clutch will engage then try and turn it to see if compressor is seized. To flush system I have a container that holds about a quart. purchased it at an ac parts supply store. Undo all lines from everything. Fill container about 3/4 full and fill with air to recommended pressure. It has a short hose on with a rubber blow nozzle. Hold the nozzle on the lines from condenser and evaporator and push the gun wash through all the components. I usually put 2 containers each way. Then blow out all components with air to get any remaining flush from system. The gun wash evaporates quickly. Then install new parts and evacuate and recharge system. Also flush hoses.
