2000-2001 Acura RL Master Window Switch: Why a Used OEM Part is Your Best Bet
A complete guide to diagnosing, replacing, and finding a quality used driver's door lock and window switch for your 2000-2001 Acura RL.
- A used OEM switch is the best option, as new OEM parts are extremely expensive (over $600) and reliable aftermarket versions are not readily available.
- Failure is common and symptoms include unresponsive window or lock buttons. Always try the window reset procedure after a battery change before buying a new part.
- Replacement is a very easy DIY job that takes less than 30 minutes and only requires a trim removal tool or flathead screwdriver.
- All OEM part numbers in the 35750-SZ3-A0x series are interchangeable, with higher numbers representing newer, but compatible, revisions.
Symptoms of a Failing 2000-2001 Acura RL Window Switch
When the master window switch begins to fail, the symptoms are usually straightforward. Because this single unit controls multiple functions, you may experience one or more of the following issues:
- One or More Windows Won't Operate: You may find that the driver's window or other windows cannot be controlled from the master switch. However, the windows may still work using their individual switches on the other doors.
- Intermittent Operation: The switches may work sometimes but not others. You might need to press a button multiple times to get a response. This can be caused by worn internal contacts.
- Power Door Locks Inoperative: The button to lock or unlock all doors may stop responding, even though the locks may still work with the key fob or by manually using the lock on the door.
- Window Lock Button Fails: The window lock button may become stuck or stop working, either permanently locking or unlocking the passenger window controls.
- No Illumination: The backlighting on the switches, which should turn on with the headlights, may go out. While this doesn't affect function, it indicates the bulbs inside have burned out.
- Physically Broken Buttons: The plastic rocker buttons, especially for the driver's window, can become loose, floppy, or break off entirely from years of use.
Pro Tip: Before you assume the switch is broken, perform a power window reset. This is especially important if you recently disconnected or replaced the car battery. To reset, go to each individual window, roll it all the way down while holding the switch, and continue holding for 2-5 seconds. Then, roll it all the way up and continue holding the switch for 2-5 seconds. This procedure can often restore control to the master switch.
Known Issues, Recalls, and Technical Service Bulletins (TSBs)
As of mid-2026, there are no active recalls or specific Technical Service Bulletins (TSBs) from Acura for the master window switch on the 2000-2001 RL. Failures of this part are generally considered a result of normal wear and tear over time, rather than a specific manufacturing defect. The most significant recalls for this vehicle generation involve the passenger airbag inflator and a brake light switch.
Buying a Used Door Lock and Window Switch: The Smart Choice
For this specific part and vehicle, purchasing a quality used OEM switch is the most practical and cost-effective solution. New OEM switches from Acura are exceptionally expensive, often costing over $600, while affordable aftermarket alternatives from reputable brands are not readily available for this model.
Here’s what to look for when buying a used switch:
- Verify the Part Number: The most reliable way to ensure compatibility is to match the part number. You may need to remove your door panel and original switch to see the number printed on it. The part numbers for this vehicle are in the 35750-SZ3-A0x series. The last two digits indicate a revision, with higher numbers being newer. All parts in this series are interchangeable.
- Inspect the Buttons: Check for excessive wear on the button graphics. More importantly, press each button. They should have a solid, tactile click and return to their neutral position smoothly. Avoid switches with loose, wobbly, or sticky buttons.
- Check for Physical Damage: Examine the plastic housing for any cracks, especially around the mounting points. Ensure the electrical connector pins on the bottom are straight and free of corrosion.
- Seller Reputation: If buying online, purchase from a seller with a good return policy and positive feedback. Reputable auto recyclers will often test parts before listing them for sale.
Warning: Do not attempt to repair a mechanically broken switch by forcing a button back into place. The internal copper contacts can become misaligned, creating a short circuit that could melt the wiring harness in your door.

Replacement Guide (DIY Difficulty: 1/5)
Replacing the master window switch is a very simple job that most DIYers can complete in under 30 minutes with basic tools.
- Pry Up the Switch Panel: Using a plastic trim removal tool or a flathead screwdriver wrapped in tape to prevent scratching, carefully pry up the edges of the trim panel that holds the switch assembly.
- Disconnect the Wiring Harness: Once the panel is loose, lift it up and locate the electrical connector on the underside of the switch. Press the release tab on the connector and pull it straight out.
- Unscrew the Old Switch: With the panel removed from the door, flip it over. You will see several screws holding the switch module to the panel. Remove these screws and separate the old switch from the trim.
- Install the New Switch: Place the replacement switch into the trim panel and secure it with the screws you just removed.
- Reconnect and Test: Plug the wiring harness back into the new switch until it clicks. Before snapping the panel back into place, turn the ignition on and test all window and lock functions.
- Reinstall the Panel: Align the panel with the opening in the door and press down firmly around the edges until it snaps securely into place.
Frequently Asked Questions (FAQ)
Do I have to replace the whole switch assembly if only one button is broken?
Yes, the individual buttons are not sold separately. The entire master switch module, which includes all the buttons for the windows and locks, must be replaced as a single unit.
Why do my passenger windows work from their own doors but not from the driver's master switch?
This is a classic symptom of a failing master switch. The internal contacts for those specific buttons have likely worn out. Before replacing the switch, check that the window lock button is not engaged and try the window reset procedure described in the Pro Tip section above.
Are all 35750-SZ3-A0x part numbers interchangeable?
Yes. The part numbers 35750-SZ3-A01, A02, A03, A04, and A05 are all compatible with the 2000-2001 Acura RL. The later numbers (like A05) represent newer revisions of the part but are functionally identical and will fit and work correctly.
Can I use a switch from a different Acura model?
No, you must use a switch specifically designed for the 1996-2004 Acura RL. While switches from other Honda or Acura models may look similar, the wiring, mounting points, and electronic logic are often different and will not work correctly.
