Are you getting them out of a wrecking yard or are you buying something aftermarket? I’m more than leery of aftermarket **** that says it’s replacement but it’s never as good as OE stuff.
Mine is an original one, no issues with the motors at all, the resistor/diode for the low speed was bad but this was on a car from the midwest, so it has a replacement one.
I don't see much of a reason to buy a new one if you can find one that isn't rusty or just plain can't find one.
