Well finally after many questions, answers, postings and testing, this issue is now resolved. Pulled the rear A/C unit, removed the side panels and made electrical tests and pressure test on the #1 compressor. Passed the electrical tests so proceeded to make a temporary addition of freon. Increased pressure held overnight so we then installed a permanent port to the front of the unit. I am lucky that compressor did not have to be replaced and not operates normally drawing about 8 amps. Thanks to all of you, especially Richard, for holding my hand. I have completed the installation of the heavy duty relays and will post under a new thread.
