Re: Heater problems
Thanks EA; I managed to get to the lower flap gearing and fixed that. It was, as I had suspected, that the sector wheel was misaligned with the gear wheel. I loosened the assembly and ran it round a couple of cogs.
I couldn't get to the heater valve. As you suggested, the centre console is screwed to the dash below the radiator and, without getting to this screw, you can move the whole assembly but not remove it as the centre console only gows as far as the handbrake lever. I'd have had to take the radio aut and, as I don't have the part, I didn't bother. I'll save that job for another day.
I still need to adjust the Bowden cable on the upper inlet flap. I might take the wipers and scuttle panel off to see if I can get to it under there.
Thanks for your help,
