Window Lift Motor - Front Right & Rear Left | 1526797-00-D

The Unsung Workhorse Behind Every Window Adjustment

Why This Motor Stands Out in Dual Roles

Adaptable by Design

• Front Right Door: Handles the heavier glass panel of the front door with a boost in initial torque, ensuring smooth movement even when the window seal is tight (common in cold weather). Its gear ratio is calibrated to match the front door’s steeper window arc.
• Rear Left Door: Optimizes for the lighter rear glass with refined speed control, preventing sudden jolts that might disturb backseat passengers. The mounting bracket swivels slightly to align with the rear door’s narrower internal space.

Built to Outlast the Road

• Silent Power: A brushless DC design eliminates the buzzing common in older motors. Instead, it operates at a near-inaudible 45dB (quieter than a library whisper), so adjusting windows doesn’t interrupt conversations or music.
• Heat Management: The aluminum housing acts like a built-in radiator, dissipating heat from the motor windings. This matters during summer road trips, when repeated window use (think: passing snacks to backseat kids) could overheat lesser motors.
• All-Weather Reliability: Sealed against rain, snow, and car wash spray, it shrugs off moisture that would corrode cheaper components. Even in humid climates or freezing winters, it starts strong with no "lag" when you press the switch.

How It Talks to Your Tesla’s Brain

• Position Awareness: It syncs with the window regulator’s sensors to "know" exactly where the glass is at all times. That’s why your window stops perfectly at the seal, never slamming shut or leaving a gap.
• Safety First: If a child’s hand or a stray branch blocks the window, the motor detects the resistance and reverses instantly—all in under 0.3 seconds. No more panicky switches; it’s automatic.
• Battery-Smart: It draws power only when moving, and even then, it’s optimized to use 30% less energy than generic motors. No drain, no dead battery surprises.

When to Know It’s Time for a Swap

• The Squeak Test: If adjusting the window sounds like a rusty hinge, the motor’s bearings are wearing out. Left unchecked, it’ll get louder until it stalls.
• The Slow Crawl: Your window takes 2+ seconds longer to open than it used to. This isn’t just annoying—it’s a sign the motor is losing torque and could fail mid-movement.
• The Silent Treatment: Pressing the switch does nothing, even if you hear a faint click (that’s the relay working, but the motor’s dead).
• The Tilted Glass: If the window leans to one side when moving, the motor’s gears are misaligned—this strains the glass and could lead to cracks.

Install Smarter, Not Harder

1. Door Panel Access: Use a plastic trim tool to pop off the door panel (start at the bottom to avoid scratches). The motor is mounted near the bottom of the door frame, visible once the panel is removed.
2. Plug-and-Play Wiring: It connects via a 3-pin harness that matches Tesla’s original—no cutting or splicing. Just press the tab, disconnect the old motor, and plug in the new one.
3. Bolt It Secure: Four M6 bolts (included) lock it into place. Torque to 5 Nm—tight enough to prevent vibration, but not so tight that the housing cracks.
4. Calibrate in Seconds: After installation, cycle the window fully up and down twice. This teaches the motor its new "limits," ensuring perfect alignment with the door seal.
