Hello, I am new to the site and was wondering if someone could help me. I have a 98 dodge ram with a 5.9 and just replaced the heater core and A/C evaporator! I took the truck in to have the A/C charged and the mechanic said it would not take a charge and that the high pressure side was peaking at 450 psi! He said that there is a blockage somewhere and thinks it could be the orifice tube. I replaced the tube and took it back to the shop and they said the same thing, high pressure side is peaking at 450 psi and it will not take a charge. I have taken everything apart and blew air through every part of the system and I can not find any blockage! Any ideas what I should do next?
Valves in the compressor can be bad/defective, regardless of the compressor's age. If you are able to blow thru all other parts of the system OK, chances are you have a bad compressor. If the compressor is just a year old, perhaps you can exchange it under warranty..
