The "module" is just a double relay that changes polarity on the door lock motors. Test to be sure you have proper continuity on the driver's door module, then be sure the passenger's door and trunk motors work properly when you apply 12v and -12v to them. You can do all this directly at the plug in the passenger's foot well with a multimeter and two jumper wires. If that all works, the module is defective. If it doesn't, then the problem is probably elsewhere - bad ground, blown fuse, etc. I've personally not had great luck with solder reflows, but it's not like you made the problem worse so whatever... nothing venture, nothing gained. ;)
