QuestionMy back wiper want work. Is the motor bad?
AnswerHi Jackie,
could be the motor, could also be a stripped spline boss or even the wiper switch itself.
Depending on the model of LR you have, you should be able to determine if the motor is getting any voltage with a multimeter.
If it is getting voltage but not working, remove it and bench test it further with voltage.
IF it is not getting voltage, you have to consider the wiper switch as the cause or the appropriate fuse.
Best of luck,
