Nissan Sentra 2005 AC high pressure?
Couple of weeks ago, after flushing all lines and replacing condenser and drier and running vacuum for hour and half and checking for leaks on my Nissan Sentra 2005, I installed a new compressor with correct amount of oil and charged it with exact amount of R-134a and although I get cold air around 39 degrees and low side reads around 35, The high side reads low. 80-100.
The sellers tell me these new compressors have a control valve that regulates how much the compressor needs to work, hence low pressure reading. Is this variable displacement compressor and is this normal
or ….bad compressor?
