Heating

[phil235]

Have fixed centre vent, it now works perfectly.
Checked connections vacuum etc all seemed ok.
Took car out of garage and left car warming up heater was set on auto at 24 fan speed 1 up till warm air comes from vents that are working.
Then turned heater setting to cold and swithched on air con and then fan to 2.
After a few minutes the centre vents opened fully b lowing cold air.
All works now.

Hi
Looking back on this thread, it seems my 1991 facelift 4.0 litre car has a similar centre vent problem: nothing coming out of it, whether it's winter or summer, or you ask for hot or cold. The rest of the system is working as it should. So, what is actually at fault please?
