Air Conditioning problem
2000 Honda Civic 4 cyl Two Wheel Drive Automatic 96 000 miles
----------------------------------------------------------------
OK, i've got a duessy, this 2000 A/C system Honda civic isn't woking properly. Whats happening is the low preesure pipe gets cold when the freon goes in but then heats up after 5 mins of running. The Compressor kicks in properly, the engine idles up properly, the blower fan emits a proper amount of air, and the a/c fan works great. One thing i found to be interesting is that the low pressure dips from about 40 PSI to almost zero when revving the engine. And the high side increases to about 250-300. When idling normally it stays at 35-40 Low side and 200 high side. We hoave replaced the following : reciever/drier, evaporator, expansion valve, A/C compressor, Condensor. None of the lines are kinked. And the high side gets relly hot. It feels as if the high pressure cant get back to the low side. And is causing difficulty. Please if you have any ideas just bounce them off me... Thanks

Hi hayaks,

Seems like some internal clogging. Check rubber hoses for internal clogging due to collapsed liner.
