A blower that runs only on its highest setting may mean the resistor needs replacing. So can fan speeds that no longer respond, or no airflow on some settings. Wiring, the fan control or the blower motor itself can cause similar symptoms, so diagnose the cause first. If a failed blower motor resistor is behind the problem, part 20336 replaces it.
