94 Trans Sport Power sliding door module

Does anyone know where the power sliding door module is located in the van? I still cant get the door to open or close using interior pushbuttons, but it will work with the remote. I was wondering if there is something fried in the module the doesn't recognize the vans pushbuttons. Also, will a module from a 92 Transport be the same as a 94's?

If you mean the door that slides to open and close by itself, as far as I can see this did not happen before 1994. There is no mention of that feature in the '93 manual and before.
The problem you mention is most probably a wiring /switch problem; similar problem occurs with power windows and power locks too. You should start tracing the voltage along the circuit starting at the push button. Notice that the problem can be on the hot side as well as on the ground side. So take voltage measurements between hot wire and ground wire that usually both go through the switch; do not connect to body ground.
