Fan speed only works on speed 2

Hi! This is Bo with Car Genius at RepairPal! We're getting into the summer months and that fan better be blowing! This could be due to a faulty blower motor resistor or a problem with the climate control module. The blower motor resistor regulates the fan speeds, so if it's malfunctioning, only one speed may work. In a dual climate control system, each side has its own blend door actuator and temperature control module, so there could also be a problem with one of these components. It most likely is the blower motor and resistor but getting it checked and verified would be a good first step! If you have any other questions feel free to call us at 877-913-1554! We'll be happy to find you a certified shop in your area!
