After curing all my leaks and having the aircon working it has packed up again. The pump is not disengaging and the high pressure pipe gets VERY hot. I assume I have a blockage. Is this most likely to be in the expansion valve? Could it be a faulty drier dumping dirt into the system? I did put a new one on but not Toyota. Is there a filter to protect the expansion valve other than the drier?. Is is possible to clean the valve and what is to stop it getting blocked again?
Thanks
