Heater problem
1997 Audi A4 6 cyl All Wheel Drive Manual 130k miles
----------------------------------------------------------------
There is very little heat coming out of the dash vents as well as the defrost vents..... I am not really sure of where to begin. The thermostat seems to be working and there seems to be coolant circulating through the system. The inlet and outlet tubes at the heater core seem to be hot. Any suggestions of where to begin...?What is the layout of the system? Is this care prone to a specific problem with the heater core, thermostat, air mix door?

i imagine coolant level is ok. coolant gauge on dash read normal? can you hear the blend door moving when switching from hot to cold?

i just looked to see if there were any bulletins for this problem and there are none. now if coolant level is up to temp and heater core is not plugged there could be a problem with the outside ambient temp sensor not raeding correctly causing blemd door to be inaccurate. this is about the only thing i can see.
