Lexus 85130-48030 Motor Assy, Rear Wiper

Remove the motor and check it off the vehicle with fused jumper wires from the battery. If the motor works, check for binding linkage. If it still doesn't work, replace it. If there's no voltage to the motor, check for voltage at the wiper control relays. If there's voltage at the relays but not at the motor, have the switch tested. If the switch is okay, the wiper control relay is likely bad.

Remove the three motor mounting bolts and take the motor out of its mounting bracket on the link assembly. Installation is the reverse of removal.
