Sunroof / Moonroof: Service and Repair
Rear Edge Closing Adjustment
Open the glass about a foot, then close it to check where rear edge begins to rise If ii rises too soon and seats too tightly against the roof panel, or too late and does not seat tightly enough, adjust it.
1. Open the glass fully.
2. Remove the rail covers from both sides, and loosen lift-up guide nuts.
3. Move the guides forward or backward, then tighten nuts and re-check roof closing. The guides have pitches of 1.5 mm (0.06 in.) each and can be adjusted 2 pitches forward or backward.
Wind Deflector Adjustment
NOTE:A gap between deflector seal and roof panel will cause wind noise when driving at high speed with the sunroof open.
1. Open the sunroof and pry rail covers off both sides.
2. Loosen deflector mounting nuts.
NOTE: Wind deflector can be adjusted 2 mm (0.08 in.) forward or backward.
3. Adjust deflector forward or backward so the edge of its seal touches the roof evenlv. Deflector seal should touch the roof panel across entire front edge.
NOTE: The height of the deflector when open can not be adjusted. If damaged or deformed, replace it.
Glass and Sunshade Replacement
1. Slide sunshade all the way back.
2. Pry plug out of each bracket cover, remove screw, and slide cover off to the rear.
3. Close the glass fully.
4. Remove the mounting nuts from front and rear brackets on both sides.
5. Remove the glass by lifting up and pulling forward as shown.
NOTE: Do not damage the roof panel.
6. Remove the wind deflector.
7. Remove the sunshade as shown.
NOTE: The sunshade may be bent slightly to ease removal.
8. Install the glass in the reverse order of removal.
9. Check for water and air leaks.
NOTE:Do not use high pressure water.
Motor, Drain Tube, and Frame Replacement
CAUTION: Be careful not to damage the seats or other interior trim.
1. Remove the sliding glass and the headliner.
2. Disconnect the motor and limit switch wire harness; remove the clips securing the dome light wire harness.
3. Remove the sunroof motor by removing the two bolts and three nuts.
4. Disconnect the drain tubes.
5. Remove the ten 6 x 16 mm mounting bolts and rear hooks from the frame, and remove the frame from the car.
NOTE: You may require assistance when removing the frame.
6. To install, insert the frame's rear hooks into the body holes, then install parts in the reverse order of removal. NOTE: Install the tube clips with the ends facing the side to ease installation of the headliner.
7. Check for water and air leaks
With sunroof out of the car, remove the guide rail mounting nuts, lift off the guide rails, and remove the cables with rear brackets attached.
NOTE: Fill the groove in each grommet with sealant and apply molybdenum grease to the inner cable.
Rear Bracket Disassembly
1. Remove the side guides from the rear brackets.
NOTE: Replace the guides with new ones whenever they are disassembled.
2. Pry the E-clip off the pin, and remove the rear bracket from the cable.
Drag Check (Motor Removed)
Before installing the sunroof motor, measure effort required to open sliding glass using a spring scale as shown.
CAUTION: When using the spring scale, protect the leading edge of the sunroof with a shop towel.
If load is over 98 N (10kg, 22 lb), check side clearance and glass height adjustment.
Wind Deflector Installation
Installation is done in the reverse order of removal. When installing, make sure to insert the deflector ends tightly into the guide rails and arrange the deflector and rails in parallel.
Closing Force Check (Motor Installed)
1. After installing all removed parts, have a helper hold the switch to close the sunroof while you measure force required to stop it. Attach spring scale as shown. Read force as soon as glass stops moving, then immediately release the switch and spring scale.
CAUTION: When using the spring scale, protect the leading edge of the sunroof with a shop towel.
Closing Force: 196-245 N (20-30 kg, 44-55 lb)
2. If force is not within specification, install a new lock washer, adjust the tension by turning the sunroof motor clutch adjusting nut, and bend the lockwasher against the adjusting nut.
