I have a 2002 Tahoe, 4wd, 5.3L w/rear a/c. Just replaced the entire a/c system (compressor, drier, condensor, expansion valves, etc). All was working great. A week later the battery died. After installing new battery now only the rear a/c works. The front will blow out of top vents by windshield but no other front vents have any air output. Did something short, or does anyone know what to look for to fix? thanks.
