SOURCE: fan control for air conditioning and heater

A faulty blower motor resistor is more than likely the culprit. Follow blower wires back from blower motor to nearest connection which is normally the resistor pack. Replace resistor.

S430 w220

P0410 is: Secondary Air Injection System Malfunction.
This may be caused by water being collected ib the Air pump or the vent solenoid and frozen or corroded the pump, also could be a blown Air pump fuse caused by the pump freezing up.

Replace the Air pump and the one-way check valve.
Replace the Air pump inlet hose.
Replace the Air pump fuse locayed under the hood.

I hope this helps you out....
