Neeseelily Power Window Switch Left Driver 3-Pack — 8‑Pin Direct-Fit for Can-Am Defender HD/Max

The Neeseelily left driver power window switch (PN 710004979, replaces 705800048) is a direct-fit replacement switch sold in a three-pack for compatible Can-Am Defender HD models.

This replacement power window switch provides a purpose-built option to restore window control on Can-Am Defender UTVs when the original switch is worn, cracked, or no longer responsive. Designed to match the electrical pin layout and mounting footprint of the OEM unit, this switch offers a practical spare-parts solution for owners, mechanics, and fleet managers who need a reliable, cost-effective replacement. The pack contains three identical switches so you can service multiple vehicles or keep one as a backup.

Which Can-Am Defender models will this switch fit?

This Neeseelily switch is compatible with a broad range of Can-Am Defender UTVs where the OEM part number 710004979 or 705800048 is used. It fits left-hand (driver side) window circuits on several model years across the Defender HD, HD5/HD8/HD9/HD10, Defender Max, and Defender PRO lineups. Before purchase, confirm the original part number or compare the 8-pin connector and mounting shape to ensure compatibility.

How do I install this replacement switch?

Installation is straightforward for anyone familiar with UTV electrical panels and trim removal. Remove the door panel or access port to reach the original switch, unplug the 8-pin connector, and swap the switch while ensuring the connector seats fully. Reassemble the trim and test window operation before finalizing the panel fitment.

• No special tools required beyond basic trim tools and a screwdriver
• Plug-and-play 8-pin connector designed to match OEM wiring harness
• Test switch function for raise/lower and lock features after installation
• Keep replacement switch secure in mounting slot to avoid vibration-related issues

What are the quality and package details?

Each switch in the three-pack is bench-tested prior to shipping to verify electrical continuity and actuation. These units are aftermarket replacements and not factory originals; however, they are manufactured to match the critical fit and function of the referenced OEM part numbers. The three-piece package supplies spares for repair shops or multiple vehicles.

• Pack contents: three (3) left-hand driver power window switches with 8-pin connectors
• 100% tested for basic functionality before shipment
• Aftermarket replacement — designed to replace OEM PN 710004979 / 705800048
• Durable plastic housing intended for typical UTV cabin conditions

Will this switch restore all window features?

The switch is built to operate the left driver window functions that depend on the single 8-pin connector it replaces. It restores manual electrical control of the window; features tied to body controllers or unrelated wiring faults will not be fixed by replacing only the switch. If windows still do not operate, check fuses, wiring harnesses, and the window motor for separate faults.

• Restores mechanical switch control for the left driver window circuit
• Does not replace or repair wiring, fuses, or window motor failures
• Confirm vehicle’s wiring integrity if problems persist after replacement
• Use with OEM-compatible connectors to ensure proper signaling

Who is this for: This three-pack of Neeseelily replacement switches is aimed at Can-Am owners, maintenance shops, and fleet operators who need an affordable, tested replacement for the driver-side power window switch. If you maintain multiple Defenders, perform roadside repairs, or want spare parts on hand, this set supplies immediate replacements that match the OEM connector and mounting style.
