| Air distribution control problem |
|
Hi guys
I'm new to the site so not sure if I've posted this in the right place.
Having problems with the heater controls disco 3 2006, windscreen vents don't work when I select the correct button and the defrost PROG also doesn't get the air out of them either! The fan is working and all other vents are pushing out hot or cold air as required?
Totally lost for a solution anyone had a similar issue and know of a fix its just like the windscreen vents are staying closed.
When I first start the disco the PROG button flashes for a few seconds before anything happens although this could have nothing to do with it.
Help and advice greatly appreciated
Thanks
Kelvin

I would say same problems as I had when I bought mine... windscreen vents not working.
There's numerous blender motors that control the vents around the car and also ones that do the temperature, which are time consuming to get to as alot of the dashboard has to be removed. PM me your email address and I'll send you the how-to that I've done.

Have you tried the HEVAC self-test procedure?
"With ignition off press and hold the ECON & RECIRC buttons whilst turning ignition on (no need to start car).
The control module will then compare the current HEVAC actuator motor positions with the values stored in the module and will indicate an error by flashing the ECON LED.
If there are no errors, the LED will go out and the system will function normally.
To confirm that there are no errors, turn the ignition switch to the OFF position, then back to the ON position.
Observe the operation of the programmed defrost LED.
If there are errors present, the programmed defrost LED will flash and the system will attempt to calibrate itself."

True, worth trying first  I've never been confident enough to try that in case it goes horribly wrong!
