That is the problem with component repair on these boards. Nobody has a full schematic except the company that makes them and folks who have reverse engineered them during repairs.
Possibly he could trace the working sides trigger signal back to the main chip and see what's in that signal path. It should be the same components as the dead side.
I would expect a smaller transistor being used to trigger the MOSFET he replaced.
Chrysler P04748376AD is the units part number, that turns up quite a few on Ebay.
Chrysler P04748374AC is the software updated version you have. Both are valid numbers. You might buy one and use it as a guide to repair yours.
