If the compressor is coming on and the pressure stay the same, then it is bad and you need another one. Here is a general guide to help and a video to show how to vacuum down and recharge the system with instructions on how to remove the compressor in the images below.

Check the system for debris inside the tubes and if so you will need to flush the system and replace the expansion valve block, also replace the receive dryer. Remove the drive belt and disconnect the battery first. Check out the images (below). Let us know if you need anything else. Ken
