Heating system frozen!

The heating/ac system in my 2000 A4 Audi wagon is frozen. i cannot turn off the fan or change the temperature setting or simply turn off the system

You can pull the fuse marked “heater” until you see your friendly Audi Dealer…

Yeah, let me guess-it has 50-60,000 miles on it. There must be an HVAC controller or relay that needs replacing but I shudder to think what the cost is.

thanks for your reply even if it’s upsetting.

When you go to the dealer bring au di money.

You’re right. I wish I had it!
