I paid $8 each at the junkyard for the window motors. These motors rarely (if at all) fail, and since they only make 1/2 revolution, they will last longer than the car lol. The lever ataches directly to the drive of the motor, and an adjustable link goes from the arm to the wing. The whole set-up is about 6" long. It is designed to stop the motor mechanically in the up and down position, not electronically. The system is controlled by a single momentary switch, and a single DPDT relay.
OK, so you mounted two motors, made two adjustable linkages and control it with a momentary switch and a relay. This gives you a manually activated drive only and while using a momentary switch you somehow change direction of the batwings so they go down too.
There is no electric limit switch to turn the electric power off to the drive so it is possible to continue powering the motor at end of travel and you rely on a mechanical stop to prevent over-travel.
The batwings do not open when the cooling system requires, only when you want them to open.
My suggestion requires only one motor drive, the addition of two end of travel switches, two more relays, and a cross shaft to match your system. Add a temperature switch and they will work like they are supposed to.
I guess that would be too complicated to make them work like they should.
I'm glad you like your batwings and I'm sure they work just fine.
You really need to be more open to ideas and see them for their worth.
