Heater problem
2001 Volkswagen Passat 6 cyl Front Wheel Drive 38000 miles
----------------------------------------------------------------
Heater only produces warm air regardless of temp setting.Dealer says it might be water pump or maybe the heater core or maybe the switch.System turns on normally and fan runs normally.
All dealer solutions seem very expensive.Are there any simple tests or tricks to solve problem?

Hi there,

This can be a couple of things. How is the engine temp? If lower than normal your thermostat may be faulty. Feel the hoses going into the heater, if both not hot (with heater on) the heater tap or controls may be faulty and not opening up the tap fully, or the core may be blocked. Check these first.
