1. Remove the trim panel - rear door. < Refer to «REAR DOOR»(ref-560372-S30456547952013061300000) , REMOVAL, Door Trim. >
2. Remove the sealing cover - rear door. CAUTION: Carefully remove the butyl tape. Excessive force will easily break the sealing cover - rear door. If the sealing cover - rear door gets broken, replace it with a new part. Remove the screw to remove the bracket - door trim rear. Carefully remove the butyl tape to remove the sealing cover - rear door.
3. Attach the battery ground cable and the switch - power window, and turn the ignition to ON.
4. Remove the glass assembly - rear door. Operate the switch - power window sub rear to move the glass assembly - rear door to the lowest position. Remove the screws and bolts, and then remove the sash COMPL - rear partition. Remove the glass - rear door partition. While tilting the glass assembly - rear door, remove the guide from the roller of the regulator and motor assembly - rear, then remove the glass assembly - rear door. CAUTION: Avoid impact and damage to the glass assembly - rear door.

1. Disconnect the connector of the motor - rear.
2. Check the motor operation when battery voltage is applied between terminals of the motor - rear connector. LH side Terminal No. Inspection conditions Standard 4 (+) - 1 (-) Apply battery voltage between terminals. Increase 1 (+) - 4 (-) Apply battery voltage between terminals. Decrease RH side Terminal No. Inspection conditions Standard 3 (+) - 6 (-) Apply battery voltage between terminals. Increase 6 (+) - 3 (-) Apply battery voltage between terminals. Decrease
3. If it does not operate properly as a result of inspection, replace the regulator and motor assembly - rear.

1. Disconnect the ground cable from battery. (Models with wiper deicer)
2. Remove the trim panel - front pillar UPR. < Refer to «REMOVAL»(ref-560372-S29988799122013061300000) , Upper Inner Trim. >
3. Remove the cowl panel assembly. < Refer to «REMOVAL»(ref-560372-S18074454952013061300000) , Cowl Panel. >
4. Disconnect the wiper deicer connector. (Models with wiper deicer)
5. Remove the molding - front window from the glass - front window, and attach protective tape on the body side of the circumference of the glass - front window.
6. Remove the glass - front window. Apply sufficient amount of soapy water to the adhesive part and insert the windshield glass knife. While holding the edges of the knife and the glass - front window at a right angle, move the windshield glass knife parallel to the edge of the glass - front window, and cut the adhesive along the surface and the edge of the glass - front window. CAUTION: Cutting of adhesive part should be started from an area with wider gap between the glass - front window and the body. Never twist the windshield glass knife. Disconnect the locating pin - front window, and remove the glass - front window. NOTE: The locating pin - front window are bonded to the corners of the glass - front window. Use piano wire to disconnect the pins.

1. Prepare the following checking items. Liquid crystal thermograph sheet (Approximate Size: 300 x 300 mm (11.8 x 11.8 in) and thermal temperature: 35 - 40°C (95 - 104°F)) Aluminum foil
2. Turn the ignition switch to ON.
3. Turn the defogger switch to ON.
4. Push the liquid crystal thermograph sheet from the outside of the glass - rear window. NOTE: Use the liquid crystal thermograph sheet every range it is separated with the separate line.
5. Determine the faulty heat wire by checking the color of the liquid crystal thermograph sheet. Liquid crystal thermograph sheet Criteria Change occurred (red --> blue) Normal No change (black) Open NOTE: Check from the inside of the glass - rear window if the liquid crystal thermograph sheet does not change. The time for the color change may differ depends on the surface temperature of the glass.
6. Wrap a piece of aluminum foil around the tip of tester probe and press it against the heat wire with your finger.
7. To both ends of the section that has been found to include an open in the step 5 ), apply the tester positive (+) probe and the negative (-) probe.
8. Move the tester probe on the negative (-) side slowly along the heat wire. If voltage changes from zero while moving the tester probe, heat wire is open at the voltage change point.
9. Repair the heat wire that determines the place of the open circuit. < Refer to «REPAIR»(ref-560350-S36693157722013061300000) , Rear Window Defogger System. >

1. Clean the broken portion with alcohol or white gasoline.
2. Mask both side of wire with masking tape.
3. Apply the conductive silver composition to the broken portion. Conductive silver composition: by Permatex QUICK GRID
4. Dry using a dryer after applying the composition.
5. After repair, check the wire.

Refer to "HEAT WIRE INSPECTION" of "Rear Window Defogger System". < Refer to HEAT WIRE INSPECTION , INSPECTION, Rear Window Defogger System. >

Note. Heat wire inspection needs removing/installing procedure of instrument panel assembly.
