any chance u know what wire i should be looking at? do i remove the whole door frame plastic thing or just remove the switch itself?

some info: 1990 ls400 little info: ALL WINDOWS ROLL DOWN AND UP ON THEIR OWN SWITCH problem: master window switch rolls down and up ALL windows EXCEPT passenger rear. basically means driver can roll down passenger rear window but CANNOT roll up. checked all my fuses everything seems to be correct, under steering wheel AND the engine fuses Can i use a master switch from 90-00? or 90-94? or only 90-92? OR if its not the master switch, could it be the passenger rear switch itself that needs switching? ive tried 1 other master switch from junkyards (could of been damaged not sure 100%) but same outcome as original master switch problem any advice/ tips!?
