Trouble Shooting

Before proceeding with specific testing, check the following for proper operation:

• Check courtesy light and CTSY (15-amp or 20-amp) fuse for proper operation.
• Check power seat system operation. Ensure power accessory circuit breaker is okay.
• Check and ensure grounds are clean and tight.
• Manually operate door locks. Ensure lock rods and lock mechanism function are normal.
• Examine sliding door contact switch for damage.
• If power accessory circuit breaker opens when power door locks are operated, check for possible short to ground.
• 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, and if possible, should be checked by monitoring voltage drop with system operational (under load).
• Check for proper installation of aftermarket electronic equipment.
