Mine is a Summer only car so while trying to reduce the cockpit temps I found the HCV was missing it's motor. So I decided to go manual control for the HCV, Flap motor works AFAIK.

cool

In the bottom picture do we think the broken 10 tooth gear and the 60 tooth gear it sits on are a single component or the two gears are glued together?

OK think it's probably easier to just replace the whole motor and gearbox as one unit.

I need one of these but with the potentiometer removed as I'll continue to use the separate micro switches triggered by the control arm. However these are now no longer available so what can I use instead??

Will the little cog come out of there Mike?
I'd be inclined to make another cog - perhaps using sugru or take a mould from it and make one from GRP

Managed to fix the water valve motor by salvaging the good 10 tooth drive gear and 30 tooth spindle gear from the airflow direction motor. How water valve now works perfectly and stops on the micro switches as it should!

With the airflow motor I managed to aligned the 30 tooth spindle gear so the broken teeth were on the opposite side to the 10 tooth drive gear so they never get used (as the airflow spindle only turns through 90 degrees max. For the broken 10 tooth drive gear on the airflow motor, this now works ok from micro switch to micro switch with a small hesitation at a couple of points where the missing drive gear teeth mean you have to wait until it turns through to the good teeth again. So works with a couple of hesitant points.

If the airflow gears do finally brake at least that's much easier to remove and replace that the hot water motor, so all ok for now
