I am kind of late to the party on this upgrade. I have wired a door with the following diagram: I have bench tested this using a DeWalt 12v battery and a 50amp battery charger. The window goes down and up, but I do not have express down. I picked 6 of the modules at the junkyard and all of them act the same. I even wired it using the Ford window module: I still get down and up but no express. I tried several of the Ford modules also. Any ideas on what I'm doing wrong? I have not tried hooking it up to an actual battery.
