Trouble Shooting

Before proceeding to TESTING  , perform the following visual inspections:

• Check POWER WINDOW CIRCUIT BREAKER for damage. Replace if damaged.
• Check power window voltage supply fuse. If fuse is blown, service and repair source of overload. Replace fuse.
• Check for mechanical failures or binding linkage.
• If express down feature does not work, but window moves down with each switch depression, replace left window switch.
• Check for broken or partially broken wire inside insulation, which could cause system malfunction but prove good in a continuity/voltage check with system disconnected. These circuits may be intermittent or resistive when loaded. Check by monitoring voltage drop with system under load.
• Check for proper installation of aftermarket electronic equipment.
