I took your advice, but no luck.

OK, so then I unscrewed the actuators from the doors, took the metal linkage out of them and left them hanging down loose from the door panels. I decided that I needed to know whether the linkage was the problem, or whether it was a wiring problem.

Now, if I pull out on either actuator, I hear click, click, click repeatedly from the relay ...but the other actuator does not respond at all. I took out a voltage meter and tested the purple wire going to each actuator. The purple wire carries 12V from the battery, and it is always hot. That makes sense. Both actuators do receive juice constantly. Now I am really stumped, but I have narrowed it down to a wiring problem, I believe.

What the heck could I be missing?

Thanks in advance.
