Our Genuine Part is brand new and has all the latest updates. The part is designed to never fail again. Of course, nothing is perfect, so we back it up with our industry-leading warranty in case something does go wrong. This part is made by the same company that made your vehicle, so you know it will be a 100% perfect fit every time, and the quality will be spot on.
Avoid the hassles of aftermarket and cheap imitation parts. Our Parts just fit right, and just work right every time.
Many of our customers are reporting an install time of around 20 minutes or less. This is really easy to install. If an installation video is available, you will find it here on this page. We are adding new videos all the time so check back later.
Does it fit my ________???
Our Parts are heavily researched and tested. They only fit the models and options listed here. Many parts look the same in photos, but in reality, they are very different. Avoid a return. Please do not purchase if your exact vehicle configuration is not listed, we can promise you it will not fit.
Simply return your part in the exact same condition and packaging that you received it in within 30 days for a full refund of the purchase price of the part, minus the original shipping charges. You don't even have to contact us. Just be sure the read the requirements below before you purchase.
Believe it or not, this is super important! Don't throw away the packaging. Manufacturers won't accept returns on a part without the genuine OEM Packaging, so we won't be able to credit you. (Even if the part is brand new with no packaging, we would have to return it to you).
Electrical parts can only be returned if they have not been installed, programmed, or plugged in. If the part shows signs of an attempted install we will be unable to accept your return.
An electrical part is any part that plugs in, contains a switch, sensor, circuit board or electrical wiring.
