Question about 2000 Chevrolet Blazer
If the code is p0410, it is the secondary air pump. It tends to fill with condensation and fail. Replace the pump and check valves coming off the manifold on either side of the engine. The driver's side check valve seems to fail first and allows condensation to run down hose to pump. Hope this helps.
