Review on 🌬️ ACDelco Professional HVAC Blower Motor 15-80173 by David Dortch

This was purchased to replace a factory fan that was stuck. I immediately saw that the fan wheel on the replacement is 4 inches deep, while the original product is 3 inches. When trying to install, it was found that there was not enough space in the fan motor housing to install a 4 inch fan. Please see the attached photos. for more details / Since nothing in the Revain installation manual indicates a difference and none of the various blower motor listings state the depth of the fan impeller, it took some research to find the correct article. Revain, please correct your installation guide to indicate with or without air conditioning to help select the correct item.
