Power Windows: Notes

Verify customer complaint by operating power window system. Visually inspect for obvious signs of mechanical and electrical damage. Inspect for blown fuses and damaged relays. Inspect for loose or corroded connections, damaged wiring harnesses and/or switches. Check for a broken or partially broken wire inside insulation, which could cause system malfunction but prove good in a continuity/voltage check with system disconnected. Ensure any aftermarket electronic equipment is properly installed. If fault is found, repair as necessary.

Begin trouble shooting at Trouble Shooting Power Windows (ETACS Only)  or Trouble Shooting Hints (All Models)  . If no fault is found, perform test on suspect components. See COMPONENT TESTING  .
