Why wont 2007 Nissan Quest blower shut off?

The blower in a 2007 Nissan Quest may not shut off due to a faulty blower motor resistor, a malfunctioning climate control module, or a stuck relay. If the resistor is damaged, it can cause the blower to receive continuous power. Additionally, issues with the vehicle's wiring or a short circuit can also lead to this problem. It's advisable to have a professional diagnose and repair the issue to prevent potential electrical damage.
