The 99 aurora uses a unique AC Discharge/suction hose that comes off the AC compressor. Because of the change in motor mounts at the front of the engine, the regular (fully stocked) hose for the 95-98 models wont work. The hard line that comes off the muffler going to the evaporator needs to be near the end of the muffler by the tube coming from the compressor vs near the opposite end of the muffler. all of the aftermarket hoses has the tube coming off the muffler ear the far end of the muffler and that causes it to hit the motor mount. and theres no way to bend it to make it work
I cant find a hose for a 99 anywhere. I had my original hose repaired as a hydraulic hose repair shop but it blew out in a year.
Any ideas on where to find one? Its GM part number 256888252
