2009 Limited, the liftgate will open with no issues, but it will not close itself. The door starts going down but immediately retract up. If I give it some help down, it will close fully and latch. Is this something that can be adjusted? Or is it motor issue?

Thanks!

 

I had a little time and I had the Liftgate Module Scanned - it returns the following code: B1 883 Which is the Power Liftgate Position Sensor 1 Circuit performance...For anyone that has experience, is this an actual sensor? Or is it built in the motor assembly?
