The blower motor resistor on a 2000 Chrysler Cirrus is typically located
behind the glove box (dashboard compartment). However, to be certain, you should consult a repair manual specific to your vehicle year and model. The location might vary slightly depending on trim level or options.
To access it, you'll likely need to remove or at least partially remove the glove box. Be prepared for some fiddly work. Again, a repair manual will provide step-by-step instructions.
