Review on ACDelco 15-80550 OE Conditioning by James Hardin

OK this fixed my dead "high" speed setting that I've been living with on my 1998 Astro for the last 2 years. The setup was surprisingly EZ. Simply remove the 2 grommets holding the washer and coolant reservoirs (which appear to be fused together). Then disconnect only one hose from the cooling tank for even easier access (leave the remaining hoses if you can). The resistor is about 10 inches from the top of the tanks and you can easily see the electrical connections going to it. 2 small screws is all it holds. Apparently my resistor was already replaced by the previous owner as it fits perfectly. The entire exchange only took about 20 minutes. Now I keep my fingers crossed and hope that it continues like this!
