Frequently Asked Questions: OE 12713815-00
Which door does this switch belong to?
It is the left hand front door unit, which on a left hand drive Tang EV or Han EV is the driver's door. Left and right are taken from the driver's seat looking forward, so check the door you are actually working on before you order. If the switch giving trouble is in a passenger door or a rear door, this is not the assembly you want. The fitment table on this page will show which builds this left front set covers.
My switch panel is marked HC-3746500A. Does that match?
It does. HC-3746500A is the alternative reference for OE number 12713815-00, and both numbers describe this same left front door switch set. Electrical parts are often marked only with the supplier reference, which is why that is the number many buyers find first. If the panel you have taken out shows a number that is neither of these, do not order on a guess. Photograph the marking and send it through the quote route with your car details.
How long before it turns up?
Delivery takes 8 to 25 days from your order to your door. The packaging details are shown on this page. If the car is still usable in the meantime, order first and leave the door card alone until the part is in your hands rather than stripping it early. The shipping cost for your country is shown on this page and confirmed at checkout before you pay.
What is the switch set made of?
Plastic is the material used for this assembly, covering the housing and the buttons you press. It is supplied new by BYD. A plastic housing carries its markings on the surface, so the reference you need for checking should be on the outside of the old unit rather than buried inside it. Read it once the panel is out, then compare it against the OE number and the fitment table on this page.
Does it need finishing to match my door trim?
No finishing is needed and nothing has to be painted. This switch set is black, and it is supplied in that finish. Look at the surround in your own door before ordering, because a car trimmed in a lighter shade will show a difference at the switch panel more than in most places. If the trim in your Tang EV or Han EV is not black, use the quote route on this page and tell us what the car carries.
Why is only one version sold here?
The switch set is listed in the Original/Genuine tier only, made by BYD against OE number 12713815-00. No Aftermarket version is offered for it, so there is one option on this page rather than a pair to choose between. The unit is new. If you have found another reference quoted for the same left front door and want it checked, send it through the quote route on this page and we will see whether it lands on this listing.
