I have an R-reg Omega 2.5 V6 CDX and the climate control doesn't seem to work properly. If I set the temp low, it only blows cold when the car is moving at speed. Also, no matter what blower settings I select, the air always comes out the front vents and footwell vents. I can't get the air to blow out of the windscren vents or the rear pasenger vents.
