SUN ROOF DOES NOT MOVE, MOTOR DOES NOT RUN (ANY SWITCH)
Blown fuse No. 37 (40-amp) in underhood fuse/relay box. Blown
fuse No. 7 (30-amp) or fuse No. 17 (30-amp) fuse in dash fuse box.
Power window relay. Faulty sun roof motor. Open in White/Blue,
Black/Yellow, Green/Yellow or Green/Red wire.
Remove high mount brake light cover. 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.
NOTE: 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". See Fig. 2. 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.
