Driver's side window does not close completely. (Using AUTO UP allows the window to fully close first and then move in reverse resulting in slightly opening.)Perform reset operation B. < Ref. to RESET OPERATION B , OPERATION, Power Window System. >

SYMPTOM CHART

SymptomsInspection order
All function does not operate.Check the fuse. Check the remote control mirror switch. Check the wiring harness.
One side of the mirror motor does not operate.Check the remote control mirror switch. Check the mirror motor. Check the wiring harness.
Mirror heater does not operate.Check the rear defogger switch. Check the rear defogger relay. Check the mirror heater. Check the wiring harness. Check body integrated unit.

Note. The mirror heater operates with the rear window defogger at the same time. Refer to "INSPECTION" of "Rear Window Defogger System" for details. < Ref. to INSPECTION , Rear Window Defogger System. >

Check the mirror and mirror mount for damage.

  1. Remove the trim panel - rear door. < Ref. to «REAR DOOR»(ref-662136-S29444951182014101300000) , 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. Be careful not to allow the butyl tape to contact any trims and seats because the butyl tape, which has a strong adhesive force, is difficult to remove once it adhered. 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 position where the mounting bolts can be seen. Pull out the running channel - rear door. Remove the screws and remove the rear outer gusset cover. Remove the bolts and nuts, and remove the sash COMPL - lower. Remove the bolts, and remove the glass assembly - rear door. CAUTION: Avoid impact and damage to the glass assembly - rear door.

HEAT WIRE INSPECTION

CAUTIONUse a dry soft cloth to wipe off dirt on the glass along the heat wires with care not to damage the heat wires.

  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. < Ref. to «REPAIR»(ref-662103-S10384493462014101300000) , Rear Window Defogger System. >

  1. Clean the broken portion with alcohol or appropriate cleaning solvent.
  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". < Ref. to HEAT WIRE INSPECTION , INSPECTION, Rear Window Defogger System. >

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