Air Conditioning problem
1998 Pontiac Trans Am V8 Two Wheel Drive Automatic 178000 miles
I replaced my compressor, dryer, evaporator, and high side line. These were all after market parts of course. I did the labor myself which was pretty easy on this particular car. I took care to rub all seals with tag oil before connecting them and I had no issues with anything fitting into it's proper location. I had the system professionally vacummed and recharged. The A/C system worked great for about a month. The temperature was around 50-55 degrees coming out of the vents.
One month later it takes a long time to get cool and it's leaking water into the passenger side foot area. The dryer use to sweat and drip water now it only gets cool not cold. I can see water dripping off the hose connection under the hood leading to the evaporator chamber under the dashboard. Other than that the compressor engages and seems to be working and the cooling fans are engaging and seem to be blowing okay. The temperature coming out of the vent only gets to about 60-65 degrees now. If I take a long drive the system seems to perform a little better but not for a very long time. I have not had the system retested to see if the refridgerant level is still the same and there are no leaks.
I'm stumped? Are one of my replacement components bad or not working up to OEM specification?
