My 2000 Jetta TDI blows cold air while driving. No fun this winter! I would expect a bad thermostat; but I understand if the thermostat is bad a warning light would be lit on the dash. Is that the case?


No, this is not your case. If the thermostat is bad any warning light would be lit on the dash.
