Blower motor resistor

[first&lastKJ]

The fan in my 07 only works on 3 and 4. Should I buy OEM or aftermarket?

I just replaced mine with OEM, worked great and cheap on Amazon. No comment on longevity yet. I replaced the blower motor at same time in case tired motor winding caused the resistor failure in the first place. (but I believe these resistor packs can wear them selves out without help too)
