Title: Climate control air distribution problem
Post by Glyn on Apr 27^th, 2021, 12:39am

Cosworth saloon.
Climate control fine until 3 weeks ago then stopped air flow to the windscreen. All other functions appear normal.
Resets have no effect
Tried different cc panel-no change.
Not done any work on it recently such as removing the dash.
When changing to screen flow I can't hear the motor going.
Where do I start to investigate?
All suggestions gratefully received

The air distribution flaps are moved by stepper motors - looking at the manual it should be possible to remove and test these without having to remove the dash - although it may be a job for a contortionist... Maybe it is just a bad connection in the multiplug ?

Not the same problem, but also CC related.
After not driving the car during winter, I`m barely having any hot air coming from the vents. It`s just cold air coming through. I don`t suspect the thermostat, because the gets up to operating temps as before in 5-7mins.
I`m suspecting the CC control module, because before winter it used to switch between blowing hot and cold without my input (not on AUTO settings). Maybe there is a sensor of different kind of thing I need to check also?

Try flushing the heater matrix.

In addition to Scorpio Mike's suggestion have a read of This article (http://www.fordscorpio.co.uk/aircon.htm) . Cars with CC as opposed to Air Con will adjust temperature although I note you were seemingly not using Auto.
