My 2007 Mercury Grand marquis has a bad ac compressor in it along with a hole in the accumulator. I am planning on replacing them at my shop, however, I do not have the proper equipment to pull a vacuum and to fill the system. My buddy has this equipment but not the tools or space to replace my system. My question is, if I replace the compressor, could I drive to get my system charged with out turning the system on without damaging anything? Or do I need to try and persuade him to bring his pump out to my place?
With no refrigerant in the system, it won’t even activate the compressor. But if you want extra insurance, just disconnect the electrical connector to the compressor clutch.
