Answer
Hi Mark,

all are common problems with LR's.  Rear wiper motor may be at fault and the best way to resolve this is to remove and bench test it.  If you apply 12v and it works, you've got a wire or electrical harness problem.

As for windows, problems can be with the BCU, window control unit, window motors, electrical connections or harness.  Again, you'll have to remove the motor and test to see if it works 'outside' the system.  If you suspect the switch, swap out and replace with one that works to verify.

Best of luck,
