About This Part
Genuine BYD front left door window regulator (OE 12581818-00, also EL-6104100) comes complete with the drive motor mounted on the steel rail. The power window lifter handles the front left glass on the BYD e3 2019-2026, e2 Glory 2019-2025 and e2 2019-2025. Guide rail, cables, motor and brackets ship as one assembly, so the door glass regulator drops straight into place. Choose this left-side unit to fix a window winder that binds or fails to hold the glass.

Frequently Asked Questions: OE 12581818-00
Is this the driver's side or the passenger side?
Front left. This one fits the front door on the left side of the car, which is the passenger side on a right-hand drive vehicle and the driver's side on a left-hand drive one. Regulators are handed, so the front right unit is a different listing and will not fit this aperture. Before ordering, look at the number on the unit currently in the door and check it against OE 12581818-00. That one check saves stripping the door a second time.
My regulator is stamped EL-6104100. Is that this part?
Yes. Both EL-6104100 and 12581818-00 apply to the same front left regulator, so either one leaves you on the right page. Old assemblies often carry a supplier label as well as a stamped number, and the two rarely agree with each other. Read everything you can find on the body before deciding it is the wrong item. If none of it matches either reference, send the numbers and your car details through the quote route on this page and the reference will be checked against them.
How soon can this be with me?
Two dates matter. Delivery takes 8 to 28 days from your order to your door. If you need to know where this OE number sits right now, for instance because the door is already apart and waiting, ask through the quote route on this page rather than ordering and hoping. The shipping cost for your country is shown on this page and confirmed at checkout before you pay.
What material is the regulator?
The material is listed as metal. That is mostly good news in transit, since the assembly will not be pushed out of true by the packing, and it means the unit can be offered straight into the door when it arrives. Support it along its length rather than by one end when you lift it clear of the box, and put something over the painted door edge so the metal does not mark the paint on the way in.
Is an Aftermarket version available for this door?
Not at the moment. Only the Original/Genuine tier is available for OE 12581818-00, made by BYD, and no Aftermarket line has been priced for this number, which is why the page carries one option instead of two. It reflects what has been sourced and no view about which would be better. Should you want us to hunt for an alternative for the front left door, send the OE number and your vehicle details through the quote route on this page and you will get an answer on what can be found.
