When pressing the driver side slide door button from remote, overhead or at door all that happens is a beep. I also noticed that when locking and unlocking the vehicle using the main switch all close but that door. I can unlock it manually. Passenger side works fine. I checked all the fuses in the rear cargo and all were good. Removed the slide door cover did not see anything broken. Slide door glass works fine. Here is some live data. Also, when I checked for codes only found one for that door and 2 for the other. Deleted both and tried doors and none came back. I think they are there from maybe when the battery was low before. cAR STARTS STRONG NO BATTERY ISSUES NOW. I hear people talk about the motor actuator, is that the same as the slide door actuator? I cannot tell if each sliding door on this car has both a locking/unlocking actuator and then a separate slide motor, it's a bit confusing, especially that what I see when I removed the cover is this big piece which I believe has to do with locking and unlocking with a bunch of locking unlocking cables, not sure if it's the same as the slide door motor.

Yep, you will have this problem if the door has resistance to move that is why you are getting the pinch error, I would coat the cable and slides down with WD40 and then clear the codes. Please let me know what happens.

There is no resistance to move the door actually, it's very smooth and the cable looks good and track is clean, cleaned more and sprayed lubricant same thing, just beeps. Is the front door lock controller the same piece that slides the door? The thing is when you lock the doors all work except that one and am sure that affect it. I checked all harnesses and all have power and ground, but not sure which piece controls the sliding door. Is the slide door motor under the door cover or in the rear?
