I am having major problems with the air conditioning on a 2001 CHEVY TAHOE 5.3L 129,000 MILES. The front is cooling at 37 degrees but I can't get the rear air to do anything but blow hot air. Yes I have changed the rear expansion valve. HELP! Everything else to do with A|C is new on this truck. What am I doing wrong?
