so one of my headlight door actuators quit, and I replaced it with a new one and all was working perfectly. The doors open perfectly, but now, all of the sudden, when I shut off the headlights, the doors start to close, but stop about halfway and then return to the full open position. If I push up the RPMs, then the doors close properly, but they will not close at idle. any thoughts?
