1997 Audi A6 no heat from heater

Is the divertor damper moving from heat to cool and back to heat when you change the controller?

Hello -

To better assist you please let me know if your vehicle is an A6 Sedan, Wagon, Quattro Sedan or Quattro Wagon. And you do have the 2.8L engine. . .. . .

So I better understand. . ...why did you have all of those items changed in the first place. . ...because the car was not blowing any heat?

When they installed the thermostat. . ...do you know if they made sure the bleeder was on top per the pic below.

How does the temperature on the engine look. . ...where it normally should, higher, lower, fluctuates?

Was the engine temperature doing anything different before you had the other work performed?

Please go to Auto Zone (AZ) or O'Reilly's (OR) and for FREE they can pull the codes to the car. Most important: Once they check your codes, if they find something and you don't get it fixed and need to get back with us, please make sure you tell us exactly what the code was, number and all. Example, if the code was E0568 O2 Sensor bad. Then make sure you give us all of that. While there for FREE also they can bring their tester out and check your battery, alternator and starter.

Please answer the above so we can better assist you.

Hello -

Let us know what you find out from AZ.

It is possible it came on and went off... So it isn't staying on..... Maybe they will test it that way. Is there an AZ anywhere else?
