Honda Accord Sun Roof: maintenance, tests and more
To see the original article with images check it out here: Honda Accord Sun Roof: maintenance, tests and more. Garage411.com
Some Accord models are equipped with a glass sun roof. This unit may also be referred to as a moon roof. Power sun roof is operated with ignition switch in "II" (ON) position. Sun roof slides rearward on all models. A permanent magnet type motor is used to operative a cable drive to open and close sun roof. If sun roof power drive fails, sun roof can be operated manually by using a socket inserted through access hole near drive motor.
MAINTENANCE
Periodically, pour a small amount of water into drain rails at edges of sun roof to ensure drain tubes remain clear. Water should drop from drain tubes at rear of right front and left rear wheel wells.
Periodic lubrication is not required. When components are removed for repair or replacement, apply multipurpose grease lightly to all moving parts, except cables. Use molybdenum grease on cable assemblies.
SUN ROOF HEIGHT
Roof panel should be even with glass weatherstrip within 0.02-0.06" (0.5-1.5 mm). If adjustment is required in front, pry out rail holder cover and loosen nut. Install or remove shims between frame and sunshade rail holder. If adjustment is required in rear, install or remove shims between guide rail and sunshade rail.
WIND DEFLECTOR
Open sun roof. Pry rail covers off both sides. Loosen mounting nuts. Adjust wind deflector forward or backward so deflector seal touches roof panel evenly across entire front edge. Measure wind deflector height from top edge of deflector to roof panel at center of deflector. Wind deflector height should be 0.7" (17 mm). Deflector arm cannot be adjusted. If arm or deflector is damaged, replace wind deflector assembly.
FUNCTION TEST
1. Carefully pry sun roof switch/cruise control switch out of instrument panel. Unplug connectors from switches. Connect jumper wire between Green/Yellow wire and body ground. Turn ignition switch to "II" position. If sun roof opens, check switch. If sun roof does not open, check foe open in Green/Yellow wire. Repair or replace as necessary.
2. Connect jumper wire between Green/Red wire and body ground. Turn ignition switch to "II" position. If sun roof closes, check switch. If sun roof does not open, check foe open in Green/Red wire.
3. Using an ohmmeter, check for continuity between Black wire and body ground. If no continuity exists, check for open in Black wire. Repair as necessary.
MOTOR TEST
Remove headliner. Unplug 2-pin connector from the motor. Using jumper wires, connect connector terminals to battery voltage and ground. Check for motor operation. Reverse jumper wires and retest. Replace motor if it does not operation in both directions.
RELAY TEST
Sun roof system is equipped with separate relays for opening and closing functions. Remove sun roof relay from dash fuse/relay box. Test continuity with an ohmmeter. Continuity should exist between terminals "B" and "C". Using jumper wires, connect terminals "D" and "E" to battery voltage and ground. If continuity does not exist between terminals "A" and "C", replace relay.
SWITCH TEST
Carefully remove sun roof switch from instrument panel. Using an ohmmeter, check resistance of switch terminals with switch in indicated positions. If continuity is not as specified, replace switch.
TROUBLESHOOTING
All models are equipped with Supplemental Restraint System (SRS). SRS wiring harness is routed close to instrument cluster, steering wheel, and related components. All SRS wiring harnesses are covered by Yellow outer insulation. DO NOT use electrical test equipment on these circuits. Before working on steering column components, disable air bag system.
Ensure all component terminals and ground connections are clean and tight. Check possible faults in order listed. Repair or replace components and circuits as necessary.
SUN ROOF DOES NOT MOVE, MOTOR RUNS
Clutch out of adjustment. Foreign matter jammed in guide. Outer cable not properly attached.
SUN ROOF DOES NOT MOVE, MOTOR DOES NOT RUN (ANY SWITCH)
Blown fuse No. 31 in underhood fuse/relay box. Blown No. 5 fuse in dash fuse box. Faulty sun roof motor. Faulty sun roof switch. Open in Green, Yellow/Green, Green/Yellow or Green/Red wire.
SUN ROOF DOES NOT MOVE, MOTOR DOES NOT RUN (OPEN SWITCH)
Faulty OPEN relay. Faulty CLOSE relay. Faulty sun roof switch. Open in Green/Yellow or Green/Red wire.
SUN ROOF DOES NOT MOVE, MOTOR DOES NOT RUN (CLOSE SWITCH)
Faulty CLOSE relay. Faulty OPEN relay. Open in Green/Red or Green/Yellow wire.
REMOVAL AND INSTALLATION
DRIVE CABLES
Remove sun roof. Remove motor from sun roof frame. Remove guide rail mounting nuts. Lift off guide rails. If necessary, remove sun shade rail and drain seal from frame. Remove inner cables with sliders attached. To install, reverse removal procedure.
DRIVE MOTOR
Remove headliner. Unplug motor harness connector. Remove mounting bolts and nuts. Remove motor. To install, reverse removal procedure.
HEADLINER
Remove sun visors, dome light, rear view mirror, pillar trim and grab handles. Remove rear seat and front passenger's seat. Recline driver's seat fully. Remove retaining clips. Taking care not to bend headliner, remove headliner starting at right rear corner. To install, reverse removal procedure.
SUN ROOF
1. Open sun roof fully. Remove rail holder cover and rail holder. Remove sun shade rail holder, deflector, link stopper and lift-up guide. Slide sun roof forward using sun roof wrench. Remove front slider from rails.
2. Lift sun shade rail with guide rail. Support rail with small wooden block to provide clearance from rail bolt. Lift glass to remove link slider from inner cable slider. Slide glass from rails. Remove sun shade in same manner. To install, reverse removal procedure
SWITCH
Carefully pry switch panel from instrument panel. Unplug connectors from switches. Remove retaining screws (if equipped) and separate switch from panel. To install, reverse removal procedure.
WIND DEFLECTOR
Open sun roof fully. Pry up rail cover and rail holder cover. Remove sun shade rail stopper and link stopper. Remove wind deflector retaining nuts and remove wind deflector. To install, reverse removal procedure. Adjust wind deflector.
