Review on 💨 Enhanced Performance: The Standard Motors RU440 Blower Motor Resistor for Efficient Climate Control by Greg Floyd

I had speed 1, 2 and 4 in my 2006 Ford F150. Here in Maine I need level 3 most winter days so I bought this product to fix this known issue. After replacing the fan motor resistor with this new product, I returned speed 3, but now speed 2 is the same as the first. So now I have speeds one, three and four instead of 1, 2 and 4. I don't think the problem is with the fan motor or fan switch in the truck so I can only assume that this product was defective. With. I could be wrong but that is my experience. If anyone can explain why installing this product didn't fix my fan speed issues, I'd happily give them more stars if the problem is something other than this product.
