Honda Fit HVAC blower fan only works on high speed due to resistor pack failure on Honda Fit

Some Honda Fit owners report experiencing issues with their HVAC blower fan only functioning at high speed, which is often attributed to a problem with the blower resistor pack. This situation can arise due to excessive current draw that leads to the failure of the blower resistor. Additionally, common causes for the AC fan blower motor malfunctioning include a blown fuse, a bad relay, or a faulty blower motor itself. Even when the blower resistor is defective, the blower motor may still operate, albeit only at high speed or stuck at a single fan setting. To resolve this issue, it is generally recommended to replace both the HVAC blower motor and the blower resistor. Furthermore, some owners notice that the blower motor may begin to degrade, contributing to the fan's limited functionality. Regular maintenance, such as cleaning the fan blade's underside, can also help prevent these blower motor issues. If you are facing this problem, it is advisable to have the blower resistor pack inspected and replaced as needed to restore normal operation.
