Not bad. Worth noting, though, that the most common cause of no cabin heat is low coolant level. Heater core is usually the highest point in the system, so a little low, and they get nothing.

The first thing to do with any overheat/no heat condition is CHECK THE COOLANT LEVEL. It could be empty, and the gauge is reading cold while the engine is melting down because the temp sensor isn't submersed in coolant.

@gdwordsmith1 It's a VAG (Volkswagen/Audi) problem; The plastic propellers fracture and the shaft just spins inside it, usually followed by a severe overheat with head gasket or engine failure.

Actually In 32 years of building custom race motors and show cars not to mention the service and repair done at several shops, I have never seen a water pump fail due to losing a fin on the pump, not one!!! most are because of bad seals and poorly maintenanced cooling system.
