Shot in the dark here, but check the output voltage from the alt/batt. Is it running low? I wonder if low output from the charging system or battery might cause a low voltage to the actuator and it won't actuate fully? Just a thought. Also from what I remember when I worked at the parts store the actuator was somewhat universal (we only carried one for GM's that you had to splice the connection onto). Is it possible that it fit but wasn't the correct one?
