If the liftgate of your 2015–2022 Tesla Model 3, Model X, or Model
Y fails to respond to button presses—getting stuck closed, failing
to open fully, or triggering "liftgate error" messages on the
touchscreen—this CFN liftgate switch (matching OEM part number
1501907-00-B) is the key component to restore smooth power liftgate
control. As an engineered replacement (not Tesla OEM), it is
precision-built to replicate the original switch’s electrical
specifications, mounting design, and button sensitivity, ensuring
seamless integration with your Tesla’s Body Control Module (BCM)
for reliable operation.
Tesla’s power liftgate relies on this switch to transmit commands:
whether mounted on the liftgate’s interior (for closing after
loading) or the rear bumper (for hands-free access on compatible
models), it sends accurate electrical signals to the liftgate motor
to control opening and closing. Unlike generic switches that may
short-circuit or misread signals, this CFN switch adheres to the
OEM’s 12V electrical rating and contact design. It also works in
tandem with Tesla’s safety features (e.g., stopping the liftgate if
an obstacle is detected) without false error alerts.
For durability, it is optimized for daily use: gold-plated contacts
prevent corrosion, eliminating the "unresponsive press" issue
common with cheap brass contacts; the ABS plastic housing resists
scratches and impacts, and won’t fade from sun exposure for
exterior-mounted switches (on Model X/Y); the button’s tactile
feedback is calibrated to avoid accidental presses while remaining
easy to use. It fits all 2015–2022 Model 3/X/Y variants, no need
for separate purchases for different models.
Installation requires no professional skills—just basic tools:
first, use a soft trim tool to remove the liftgate’s interior panel
(or the rear bumper’s lower shield) to access the switch; unplug
the old switch’s wiring harness, remove the two Torx T20 screws
(torque spec: 0.5 Nm, per Tesla) and take out the old part; align
the new CFN switch with the mounting holes, secure it with the
original screws (do not over-tighten to avoid housing cracks), then
plug in the harness until it clicks. When testing, turn on the
vehicle and press the switch—the liftgate should open/close
smoothly with no touchscreen errors.
Note: This switch is exclusively for 2015–2022 Tesla Model 3, Model
X, and Model Y. It does not fit 2023+ models (with updated liftgate
electrical systems) or Model S. It is ideal for fixing unresponsive
liftgate buttons, stuck buttons, or resolving "liftgate
communication error" messages, allowing easy liftgate access
without manual force or expensive dealer repairs.
