Good stuff Roger.
One thing to think about if you're going to the extent of tooling is perhaps a multi-cavity tool. We use a lot of plasctic pieces in the telecom world and when the parts are small the specialised tool save many $$$.
Not sure how similar rubber injection tools are to plastic.

I agree but how would you activate them?

Redesign the HVAC head to take the control signals for the solenoids to the servos which are then mounted to replace the actuators. The design would have to use servos strong enough to open and close the respective flaps. This way the auto system can remain unless one wanted to get real adventures.

I did'nt cut a hole which you see in the begining of the post which would have made things much simplier, but rathter used the vent on the passenger side.

If (and its maybe a big if but I'm pursuing it) we can replace the vacuum acuators with electric servos there's a possibility of changing the default positions. If this works what would be your preference.............my first thought is the hot water valve; default closed?
