Driver's side rear sliding door problems

Does the power door work when opening it with the handle?Those vans had a lot of trouble with the power sliding doors.

So if you unlock the door put it back in gear and do this several times will it lock again and again?If so it still wont lock with the switch or remote?A bad door lock actuator almost makes sense.

More than likely the sliding door contact pads and plungers are dirty, run a scotch brite pad over them and try it out

I WOULD TRY SHUTTING OFF THE AUTOMATIC DOOR SWITCH, THERE SHOULD BEA A SWITCH TO DISABLE THE AUTOMATIC PART. THEN TRY CLOSING THE DOOR. YOU CAN ALSO WITH THE DOOR OPEN PULL THE INSIDE DOOR RELEASE HANDLE AND AT THE REAR OF THE DOOR HAVE SOMEONE ELSE USE A SCREWDRIVER TO POP THE LATCH OPEN.

On the one that opens and closes before if finally closes have you tried cleaning the door contacts?For the one that doesnt close all the way is there extra slack in the cable in the door run channel?

Try the initialization procedure, Replacement of the PSDM requires that the Power Sliding Door System be disabled by removing the PSD 15-amp fuse. Once the PSDM has been replaced and the fuse installed, the following initialization procedure must be performed for both sliding doors in the following order:

Manually close and latch the power sliding doors.
Perform two complete Open/Closed cycles for each sliding door using any one of the following devices:
"Â Appropriate switch mounted in the overhead console

"Â Appropriate switch mounted to the B pillar

"Â Remote Transmitter

"Â Special functions of the scan tool

With a scan tool, verify that the PSD Open/Closed Position Learned parameter displays "Yes".
Operate the power sliding door to verify completion of the procedure. If this dosent work post back, may need to be scanned for codes, or may be other problems.

On the "claw" that closes is a switch that tell the system the door is open or closed, try spraying it with WD-40 and open and close it a few times.

Which door?Does it not work from the B-pillar switch?Does it work from the overhead console switch?Need more info.

I bet your problem has to do with the handle itself. I have seen lots where the plastic bracket on the back of the outside handle separated so the lock gets jammed so it won't unlock or lock.
