Power Window System: Diagnosis Chevrolet Tracker II

TROUBLE SHOOTING

Note. Some components incorporate a short wiring harness between component and harness connector. Wire color may be different from that used in main harness. See WIRING DIAGRAMS .

PRELIMINARY INSPECTION

Inspect P/W fuse (30-amp). Ensure ground (located behind left side of instrument panel, above junction block) is clean and tight. Ensure power window lock switch is in UNLOCK (released) position. Before component replacement, check for poor connections at related component and in-line harness connector terminals. If concern is still exists, diagnose by symptom. See SYMPTOM INDEX table under SYSTEM TESTS.
