I've ran into a snag on a 96 tahoe a/c, a year ago the compressor gave up,i replace the compressor, accumulator,orifice tube, expansion valve and condenser,flushed the lines and evaporator coils front and rear,it worked perfect until the other day the compressor locked up,the oil was clean and no metal was found on the orifice screen,but I flushed the whole thing again,and replaced all above parts again,I drained the compressor and refilled it both times with 8 oz's of pag 150 oil,the system was held under 30 inches vacuum according to the gauge for over 2 hours both times problem is when I get about 20 oz's of 134 in the system which isn't enough to keep the compressor from cycling too fast with the engine at 1500-1800 rpm's the high pressure will go to 350-375 psi and the high pressure switch will shut of the compressor, once it starts this the low side want drop below 50 psi because the compressor is cycling too fast,I thought I had gotten a bad orifice tube so I installed another one and still have the same problem,the rear unit is working fine it's gas flow by-passes the accumulator system,the front unit isn't working,the line from the orifice tube to the evaporator is cool and sweating but nothing else on the low side is cool or sweating,as a normal it will sweat all the way to the compressor,what could be restricting the gas flow thru the evaporator,thanks in advance for any imput on this problem

Today's Featured Article - The Day Mom Drove the 8N - by Brian Browning. My Dad was wanting to put in a garden but couldn't operate the 8N and handle the old horse drawn plow he had found and rigged up to use with the tractor. Well, he decided to go get Mom out of the house and have her drive the tractor while he walked behind the plow. You got to understand that while my Mom is a hard worker who will always help whenever she can... she had never operated farm machinery before that day. Dad got her out there, explained how the clutch was the same as in our o
