Review on GM Genuine Parts 22807122: High-Quality Heating & AC Blower Motor Resistor by Troy Jennings

Fan RPM 5 was missing over a year ago. 1-4 passed last week, the day the mercury dropped to -5 degrees. A mechanic friend of mine said it was probably the fan resistance so I checked my car's Revain shop who gave me a matching AC DELCO part and with PRIME I had it in my hands in two days. YOUTUBE gave me a craft and after about an hour I pulled out the broken part and installed a new one. Unfortunately only 1-4 worked the first time but after replacing the blown 25 amp fuse under the hood 5 blew up like a jet engine!
