Item Description: Front Driver Side Door Wiring Loom

Part: Front Right / Offside Door Main Wiring Harness Loom
Condition: Fully tested, intact clips, un-cut factory wiring in excellent working condition.
Material Construction: Automotive-grade copper wiring encased in flexible high-temperature corrugated PVC protective tubing, equipped with secure locking multi-pin factory connectors.

Where is this part fitted & what does it do?

This wiring loom is fitted internally inside the front driver's door (offside right) and routes through the rubber door bellows into the main cabin chassis. It controls and distributes power/signals to all critical door electronics, including electric window regulators, central door locking actuators, power wing mirror adjustment/folding motors, door speaker audio, and door-open sensor switches.

Symptoms of a Faulty or Damaged Door Wiring Loom:

• Electric windows failing to respond or working intermittently when operating switches.
• Central locking failing to lock or unlock the driver's door while other doors respond.
• Electric mirror controls failing or erratic operation.
• Door open warning light staying illuminated on the dashboard cluster.
• Blowing fuses or speakers cutting out due to internal wire breakage inside the rubber door boot.

Why replace with a verified original factory part?

Repairing broken wires inside a brittle loom is a temporary fix that frequently fails due to constant door movement. Replacing the complete assembly with a verified factory original ensures plug-and-play reliability with exact wire gauges and connector pin alignments. Plus, buying premium used parts can save you up to 70% compared to brand new dealer parts!
