Hi all, got a 2000 plate zafira, had some problems with heating system over past few months which have nearly all been resolved. When driving the car i only appear to be getting heat out of only the drivers side vent,rear centre console and drivers vent on the windowscreen. I am not getting any heat out of passenger side vent or centre console vents. why??????? Car has had new thermostat and new radiator fitted in past 2 months however this problem was there before. does anyone have ant ideas how to solve this or what the problem is. cheers
