Customer: replied 1 year ago.
High pressure not running on
Expert:  Tim's Auto Repair replied 1 year ago.

let the pressure down to 50psi with the compressor on...if the compressor kicks off or it doesnt cool..this tells me the high and the low sides are equalizing

Expert:  Tim's Auto Repair replied 1 year ago.

i would like to have the high reading as well as the low

Expert:  Tim's Auto Repair replied 1 year ago.

if the pressure is equalizing to the low,,the new compressor is bad,and you will need to replace it again

Customer: replied 1 year ago.

Expert:  Tim's Auto Repair replied 1 year ago.

I am going to reassemble it again and try tocharge your system and I will see what the readings are low and high I have replaced the compressor twice
