Ah ha. With thanks to all those that led me to the plastic clip thing for the heater flap. It was broken. Heater matrix had also been by-passed. Yesterday I found out why. Loads of heat (horay) loads of water in cab.
That was why it was by-passed. Duh
Would a repair at a radiator specialist be best or replacement from say P & H?
Is it a dash out job?
Also cheers Mike for popping round
