Same/similar type of failure is common on 90's Fords as well from my experience and probably more stuff than that. Just sayin' there could be a wider market than Z's.Helping the Z community. The blend doors for our HVAC is controlled by a small motor with an itty-bitty gear train. There's one gear in particular that likes to break, so I'm seeing if I can make new geartrain dildos with herringbone spurs, to more stably handle the strain.
The real problem is that a lot of these guys have rusty actuator arms inside that stick, but to get the geartrain out, you have to free the stuck arms anyway, so it's not likely that once these things are busted, they'll get reassembled badly.
I doubt they all design and manf. actuators, gear assemblies, etc. More likely source something already out there and common across at least some different brands.
