Troubleshooting New Beetle AC Compressor

maddogyp on Wed July 11, 2012 1:37 PM User is offline

Year: 1999
Make: Volkswagen
Model: New Beetle
Engine Size: 2.0
Refrigerant Type: 134a
Pressure Low: 90
Pressure High: 90
Country of Origin: United States

Looking for some advice. I just replaced the Compressor, Dryer and expansion valve. I used a rebuilt compressor. ( I know I know but that is all I can afford) I put everything together (4.5 oz of PAG oil in compressor) and then drew a vacuum on the system for 30 minutes. I let it sit for about an hour to make sure that there were no leaks. I then charged the system with 750 grams of 134a. (weighed the cans before and after to make sure of amount)

When i started the car, the air did not get cool. The clutch was turning and the fans were on. I drove it around and smelled a burning smell. I saw a little smoke from around the ac pulley area and it seemed like the clutch was "slipping". I thought i might have gotten some oil on the pulley so I pulled the belt and cleaned all the pulleys. I didn't get any more smell after that. I let it sit over night and the next morning I started it up and it blew cool air ( clutch was turning fine). I let it sit again for a couple hours and then tried it again and no cold air. I also noticed that the clutch is no longer turning. I can turn it by hand so it isn't locked up.

I pulled the connector off of the compressor and i have 13volts. I did a continuity test on the plug attached to the compressor and there is no continuity. I checked the old compressor and saw that there was continuity.

After that long explanation, my question is... I think i just got a bum compressor. Does anyone have an opinion or advice? It has a 90 day warranty but i wanted to hear some opinions before I go that route.

Certainly sounds like you need to use your 90 warranty.
