Check your fuses.
Check the fuses.
Start with checking for blown fuses.
There is a Relay for the Power Door Locks, which I purchased today from Checker Auto parts, but I can not find where the relay is located. I am assuming or hoping that it is the Relay for both the Door Locks and Power Windows.
Remove the power locks and windows fuse you will loose power for your windows also

It can be your battery, when it doesn't have enough power the computer will not allow you to use power stuff. It can be also one of the relays which are responsible for stuff like power locks, power windows and so on.
My door locks stopped working and I pulled the IOD fuse and reset it back after starting the vehicle. Now all locks work great to include the remote process. The IOD is mapped on the lid of the fuse box.
I would not see any way of this working. Completely two different set-ups. You have the old Sportvan and are wanting to use parts from an Express van. To say nothing of the wiring, switches & relays to convert to power windows and locks with the right parts.
