The main problem is the knobs used for the controls are connected to the various control valves by steel wire inside a steel coil not a good combo in our humid climate they often jam and then you wind up with broken controls or the wire might have come off the control valve under the bonnet or maybe the valve is jammed in the closed position with corrosion . You can see the heater control cable under the bonnet it comes through the firewall and connects to the valve its just under the water reservoir there is a hose with a fitting which is the valve its probably stuck or the cable itself is seized [this is what's wrong with my sons T4 ]

Control valve seized which in turn stuffs the plastic gearing on the dash controls either swap out or sometimes u can operate it manually in the engine bay. I kept mines seized in the cold posi for brizzyAlba European

I've been to busy using the T4 to follow up what the choke knob actually did...always saw it and thought 'that's strange' but then got distracted by doing things. So now I know...I have a heater control. Now to work out what the red rocker switch is on the dash near the steering wheel...have flicked this and it doesn't seem to do anything...?
