Review on ACDelco 15-80550 OE Conditioning by Darin Brooks

Fits perfectly on my 2005 Astro. Easy exchange. I recommend ordering a spare connector to connect to this resistor, as well as having heat shrink tubing and soldering tools on hand to connect it in place. If your fan has never been changed, maybe it's time to do so. An old fan with bad bearings can burn and/or melt the orange wire connector. Replacing the fan, connector, and resistor takes about an hour or two, and you don't have to worry about running out of heat or AC power.
