2000 Chrysler Sebring Air Conditioner/ Heater fan

I have purchased a resistor to plug into the blower motor. My motor only works on the highest setting. I have been told that tis part is the fix for my new problem.
I can't find the fan motor or where to plug in the new part. Probably not a big deal, but if I can't find it, it's a big deal to me.

Can you help, please?

Thanks,
Carl
