RE: My '87 Quattro blows! (Hot air)
1st off you need to identify what model you have. Quattro does not cut it.
But I think you have a 1986 4000 cs quattro.
It sounds like your heater valve is broken or disconnected. Easy fix. The
valve is located just above the steering rack in the middle of the engine
compartment. Check the cable operation 1st. The vents should blow cold air
out of the center only. This is a feature to some and a pain in the a$% for
others. As for the temps. They will run higher than you are probably used
to. This car has a gauge that tells you actual temperature not like the
American cars that only move when overheating. It normally runs about the
second mark down from the top and may run a little below at highway speeds.
The flashing light is most definitely that level sensor. Add a little more
coolant and it will go away.
As for the wiper washer motor sounds like you are on the right track.

I am the proud owner of a new (to me) '87 Quattro and I am having a few
minor problems with it.
I think there is something amis with the thermostat or cooling system. I
took the car for a 400 mile checkout drive over the weekend. The car
performed very well except for two things:
1) The car blew very warm air through the far left and far right vents the
entire time. This is even with the temperature control guage all the way to
the left (cool). The center vents seemed to blow cool air the entire time.
I had the selector on vents, not floor. The outside air temp. was about 60
degrees F. The reason I suspect a thermostat or cooling system problem is
because there was a large variation in the engine temp. reading on the
dash. It seemed like the car wasn't keeping itself very cool while climbing
or in city traffic even though the outside air was relatively cool. I'm
afraid of what it will do when it gets warmer. The temp guage also blinks
on and off when I go around corners when I just start the car. A friend
said there are sensors to detect the coolant reserve level but I checked
the reservoir when the car was cold and it seemed full. The air coming from
the side vents was so warm that I had to close them and open the sunroof.
2) The windshield wiper fluid motor isn't working. Digging seemed to
indicate that fuse #12 was the fuse connected to the motor. is this
correct? This fuse seems to be fine. I haven't put a DVM on the motor yet.
