I have recently replaced both expansion valves the receiver drier tube, the compressor is less than 2 years old, I am able to pull -30 psi of vacuum and it will hold the vacuum. After vacuuming out the system for over 30 minutes I went to add refrigerant however it will not take more than 1/2 can. I have attempted to bypass the low pressure sensor to get the compressor to turn on but it has a 4 pin setup and I could not locate the ground to proper bypass. Any ideas, diagrams or advise is welcome. This is the second summer without a/c and We cant do it again
