[QUOTE="338Shooter, post: 1586809, member: 3449"] That is the accumulator/dryer. Dripping is probably from the evap coil and is normal. Really the only way to start knowing what is going on is to put gauges on it. At least on the low side. Start the truck and turn the AC on full blast and recirculate. See if the compressor is cycling on and off. Should be easy to tell. Then have someone rev it up to about 2k RPM and see if it cycles on and off. cycling in either situation cold mean low charge. What year is the tahoe? If it is the GMT400 like my truck, you've probably got a belly leaking compressor. Very common and a pretty easy fix if you've got a couple hundered and a couple hours. You might have a problem with your fan if it is warming up at stop lights. If the compressed freon isn't getting cooled into a liquid by the condenser it will get warm. [/QUOTE]
