Review on 🔥 ACDelco Professional 15-50664 Blower Motor Resistor: Optimal Heating and Air Conditioning Performance by Matthew Miles

This item corrected the lower air conditioning/heating fan settings. My car's air conditioning/heating only blew on high power, all other settings gave nothing. I googled this problem and found that the fan resistor needs to be replaced. I am ordering this ACDelco part as a replacement. It's really easy to replace, but push really hard to get to one of the two (Phillips) screws holding it in place. FYI I used a set of precision tools with a flexible extension. I bought this tool set from a home store a while ago for about $5. I've never had to use a flex extender, but I'm glad I have one as that fan resistor sits in a very narrow spot at the passenger's feet. I suggest you watch your car on YouTube to see what other tools people have used to get that bolt out.
