Review on GM Genuine Parts AC Accumulator 15-10421 by Paul Randall

The product was a brand new AC Delco, as in the description. Unfortunately mine was different. Be sure to compare the photos of it with those on your car. There are two styles. Mine had a big square block in front with two lines going up. The worst thing was that AC Delco no longer has this particular one so I had to go to the aftermarket. The car is a 2000 5.3L Tahoe with rear air conditioning but no rear heater.
