Technicians typically replace this part when they’re seeing leaks, visible wear, cracking, corrosion, or a component that won’t stay seated. If the fault changes with vibration or after moving panels, look for borderline fitment and loose connectors in the same area. This replacement component supports normal operation by restoring fit, sealing, alignment, or control behavior. Match the part number 02-3971-31 to the old component before ordering, then reinstall with careful alignment and routing. A correct-fit replacement helps restore predictable operation and reduces repeat service calls. If the part interacts with water, do a leak check during the first run and again after a short operating period. Clean the area around the repair so debris doesn’t interfere with fitment or sealing surfaces. Take a photo before disassembly so you can confirm orientation and fastener locations during reassembly.
