Strange simptom:
Rear blower works continuously, even though that the engine is cold (24h not driving it) and the temperature regulator is at blue dot.
But, if I push the regulator in the blue dot direction (or just hit it a little bit), the rear blower stops.
Did you ever had a similar simptom before? What might be the problem - damaged temperature potentiometer or the CCU died?

Please advice.

my rear blower runs all the time too, even when starting after 4 months of being idle--- engine is very cold

Kuchar

i think we have the same problem

Mine started doing this recently if the temp dial is not all the way to cold. Only on cold starts in the morning. Doesn't do it when the car is warm. I am all ears if anyone has an idea on what I should look for.

I will replace temperature potentiometer in few minutes. And we will see.

replaced, i am going to garage.

Done!
cause - failed temperature potentiometer!!!
Now is replaced. And rear blower starts when i move the temp dial above blue dot.
At the blue dot is off!

so even if the motor isn't running the blower runs? Should it?

edit: Ok... so I moved the dial back to the blue dot. The blower doesn't run. So I just never really understood it's function before. Now it makes sense!!! You sure can learn something if you hang around long enough
