Installation Guide

The AC246 is designed for a straightforward swap with the factory regulator. Follow these steps to ensure proper fitment:

1. Disconnect Power: Remove the vehicle’s battery or disconnect the negative terminal to prevent accidental activation.
2. Remove Existing Regulator: Unscrew the mounting bolts (typically four per side) and gently detach the regulator from the window frame. Carefully release any tension on the wire rope.
3. Align New Unit: Position the AC246 in the same orientation as the original, ensuring that the motor shaft aligns with the existing gear assembly.
4. Screw Securely: Tighten all mounting bolts to the manufacturer’s torque specification (usually 20 Nm).
5. Reconnect Wiring: Attach the regulator’s electrical connector to the vehicle’s harness. Verify that polarity matches and that no pins are misaligned.
6. Test Operation: Reconnect the battery, then operate the window controls from both the door panel and central console to confirm smooth lift and lower functions.

Maintenance Tips

• Inspect the wire rope annually for signs of wear or corrosion; replace if frayed.
• Clean the regulator housing with a mild detergent and soft cloth; avoid abrasive cleaners that could damage the anodized finish.
