Heater doesnt work, and A/C on all the time
Just bought my 2003 Audi A6 4.2 V8 Quattro but found that the heater doesnt work at all.
If the interior fan is on, then the A/C is on and only very cold air comes out. There is no effect by changing the temp settings, fan settings or A/C on or off. It appears that water is not circulating through the interior heater, even though the motor gets up to correct temp quickly. I have bled the air from the cooling system, and have reversed flushed the interior heater. It is not clogged. Any ideas for the cause ? :confused: :confused: |
Did you ever figure this out?? I'm having the same problem with my 2003 a6 3.0.... It'll be hot for a brief second and then the ac kicks on.

1. Heater hose was twisted and so no coolant was flowing through the heater. 2. Fresh air blower motor was worn and so worked intermittently. I removed the motor and cleaned the carbon brushes. Now all works fine. :) |
Awesome!! I'll give that last one a shot and see what happens!
