Review on ACDelco 15-71991 – High-Performance Original Equipment Conditioning Solution by Brent Walker

Replacement part ordered and received quickly, it came in an unlabeled box, no ACDelco branding. The appearance was identical to the original part, so I completed the installation and verification process, everything is fine. Due to the cool weather, I didn't use the air conditioning often, but when I needed to smoke, I started blowing air out of the vents. I checked in to see if I can return or get a replacement but it was too late. I ended up buying a new part at a local car dealership. Sometimes when you think you're saving money, you're not.
