Engine Size: 2000
Refrigerant Type: r134
Ambient Temp: 80
Pressure Low: 90
Pressure High: 90
2002 Jetta 2.0, AC compressor is ON, but the pressures are both the same, just like the compressor wouldn't be engaged. I am thinking that the expansion valve is stuck open, does this sound OK? Can the compressor be so bad that it doesn't make the smallest difference in pressures?
The variable displacement compressor used on that car can and does fail that way. Stuck at zero displacement.
Low refrigerant level.
Control valve if system has a proper charge level.
May check this link as this situation has been cover a few times.
So, does it look like I need a new compressor? Is there a way to test the compressor before I swap it out?
