Symptom Troubleshooting Index

SYMPTOM TROUBLESHOOTING INDEX

Symptom	Diagnostic procedure
Water leaks from moonroof	Check for a clogged drain tube. Check for a gap between the glass weatherstrip and the roof panel. Check for a defective or improperly installed glass weatherstrip or drain channel. Check for a gap between the drain seal and the roof panel.
Wind noise from moonroof	Check for excessive clearance between the glass weatherstrip and the roof panel.
Motor noise from moonroof	Check for a loose motor. Check for a worn gear or bearing. Check for a deformed cable assembly.
Moonroof glass does not move, but motor turns	Check for a defective gear or inner cable. Check for foreign matter stuck between the guide rail and the slider. Check for a loose inner cable. Make sure the cable assembly is attached properly.
Moonroof glass does not move and motor does not turn (glass can be moved with 5 mm hexagonal wrench)	Check for a blown fuse. Check for a faulty moonroof switch. Check the limit switch. Check for a run down battery. Check for a defective motor. Check for a faulty relay.

Glass Position Adjustment

The roof panel (A) should be even with the glass weatherstrip (B), to within 0+1/--1 mm (0+0.04/--0.04 in.) all the way around. If not, make the following adjustment:

Closing Force and Opening Drag Check

1. Remove the headliner (see HEADLINER REMOVAL/INSTALLATION ).
2. Closing force check:
   • With a shop towel (A) on the leading edge of the glass (B), attach a spring scale (C) as shown.
   • Have an assistant hold the switch to close the glass while you measure the force required to stop it.
   • Read the force as soon as the glass stops moving, then immediately release the switch and spring scale.

   Closing force: 200-290 N (20-30 kgf, 44-66 lbf)

3. If the force in not within specification, remove the moonroof motor (see MOTOR REPLACEMENT ), then check:
   • The gear portion and the inner cable for breakage and damage. If the gear portion is broken, replace the motor. If the inner cable is damaged, remove the frame (see FRAME AND DRAIN TUBE REPLACEMENT ), and replace the cable (see DRAIN CHANNEL SLIDER AND CABLE ASSEMBLY REPLACEMENT ).
   • The moonroof motor (see MOONROOF MOTOR TEST ). If the motor fails to run or doesn't turn smoothly, replace it.
   • The opening drag. Go to step 4.
4. Opening drag check: Protect the leading edge of the glass with a shop towel (A). Measure the effort required to open the glass using a spring scale (B) as shown.

5. If the load is over 40 N (4 kgf, 9 lbf), check:
   • The side clearance and glass position adjustment (see GLASS POSITION ADJUSTMENT ).
   • For broken or damaged sliding parts. If any sliding parts are damaged, replace them.
