Nate and others -
I stand corrected, we did use Bosch motors for Power Sliding Doors, back in the early days.

My other resource confirmed that the 16636815 is a Bosch motor. 16640238 is a good part number and it was used on the 1998 M Van (Ext Wheel base only) a different motor part # was used on the regular wheel base, RH & LH sides and that part # was 16642739.

16644829 is a Taigene motor that was used in production for only a very short period of time, after which it was replaced with a different motor that had improved EMC suppression capability. It was used on the GM Van PSD.
One of the problems with trying to find old part #'s that match kit parts, is the motors donated for the kits do not necessarily match up year wise. A 1999 Kit motor was from a previous year vehicle, a 2008 Kit motor was from some previous year vehicle application - so, it gets a bit tricky.

Also, another key important thing to remember is that the part # of the motor in the kit may have only been used in production for a very short period of time (and this is also true of the window lift and other motors). Changes occur on a regular basis, so if you are looking for a specific part number for a motor, do not get too upset if the vehicle listed doesn't have that specific part number. Changes based on government regulations, or warrenty, or product improvements require re-identification and that happens on a pretty regular basis.

The motors donated for the Kits were most likely obsoleted motors that had been supeceded by an improved version.

I hope this helps,
Mike
