Four Seasons rates this selector switch as meeting or exceeding OEM specifications, and it draws on the brand's more than 50 years of mobile A/C experience. Signs this part may need replacing include a blower that runs on some settings but not others, a blower that will not run at all, or a fan that cuts in and out. A blower resistor, motor or wiring fault can cause the same signs, so diagnose the cause first. If a worn selector switch is the problem, this unit replaces it.
