Verify Compatibility Before Purchase
Confirm that the switch layout, connector type, and mounting bracket match your existing unit.
Disconnect Battery Before Work
Always disconnect the negative terminal of the 24V battery before removing or installing the module to prevent short circuits or ECU errors.
Professional Installation Recommended
Requires disassembling the door trim panel and handling delicate wiring. Best done by trained technicians.
Handle with Care – Sensitive Electronics
Avoid static discharge, drops, or moisture exposure. Do not touch circuitry directly.
Ensure Proper Sealing & Waterproofing
After installation, ensure the door’s internal moisture barrier (plastic film) is fully restored to prevent water ingress.
Avoid Liquid Exposure During Cleaning
Use only dry or slightly damp cloths. Never spray cleaners directly onto the switch.
Test All Functions After Installation
Verify:
All window movements (up/down)
Lock/unlock operation
Mirror adjustment and folding
Mirror heater (if applicable)
Do Not Modify Internally
The unit is sealed and not user-serviceable. Opening voids warranty and risks permanent damage.
Check for Corrosion or Moisture
If replacing due to failure, inspect for signs of previous water leakage or condensation inside the door.
Use Genuine or High-Quality Replacements Only
Avoid counterfeit modules with brittle plastics or poor relay quality — they degrade quickly and compromise safety.
