Yes I am new to the forums and haven't posted much. Sorry for posting in the wrong place. Anyway yes its a 1500. 2017 silverado with about 170k. The so called new part from eBay did ha e the same markings as oem and part number. It would be nice to find parts at the dealer. Ok so when I command the shutters open/closed how does the ecm know the position. Is there a re-learn command that my scanner doesn't have the option for?
When I command it open/close it just goes till it hits the stops.
I didn't change the whole assembly just the actuator. I find it ridiculous to change the whole assembly for just a $50 or less actuator.
