ONLY COLD AIR

1996 Audi Quattro

Heater problem
1996 Audi Quattro 6 cyl All Wheel Drive Automatic 152000 miles

I only get cold air out of the heater. I have replaced the AC module and the heater control valve. What else should I check? Do I have to bleed the system? I can feel vacuum at the control valve but have no way of measuring it. Any suggestion would be great.

HI there,

Check that the heater hoses are hot with the heater on and the engine at normal temp, if not the tap may not be opening, check this first.

Finally discovered that there are twobleeder valves. That didn't work. Broke down and took the car to the shop. Enjoy the donation.
