Your problem seems to be with the passenger door module, which has the RF receiver which gets the signals from the remote controls. (its just a part of the module where the window switches are mounted on.) The question only is, with your jeep being right hand drive, if the unit is still on the passengers side (so left door in your case), or on your drivers side door module. Using the previously mentioned DRBIII scanner could tell more how the modules are working.
It could be that the respective module has a problem or even that the antenna wire broke of. You could try and use the remotes very close to where the window switches on the front doors are, try on left and on right door. If it would work in that case, then there is a good change that the problem is the antenna wire. If it still doesn't, most probably the problem is with the door module.
