And there you have it. Glad you figured it out. Now maybe the actuator is good but the connection is bad. Easier fix and less costly. Sometimes things under the dash get crud in them over time and just a good clean connection will fix. Also, make sure when you plug the harness in that the pins align and slide together tightly. Sometimes on the connection the pin on the harness will push out of the holder instead of sliding together and then either cause a bad or intermittent connection. Good luck.
