Very Satisfied
while the switch is not OEM, it looks, fits & works just like the OE. the $ saved vs purchasing the OEM is significant. even better, was the utube video for installation. the instructions are spot-on. the production quality of the vid is also excellent. even though i had my own foreign car repair shop back in the 90s, it was still very helpful the entire process took less than 30 minutes with no surprises.

Perfect replacement!
After living with a sporadically failing switch for years, my only regret is not doing this sooner! The installation video made it very easy (last step to removing old switch took some wiggling to unhook the clips on other side) and it was well worth the price and effort! Its nice to have all functions back again - auto up/down and child locks - like a new car!!

Ordering online was so easy. This was the first time using 1Aauto and I couldn’t be happier. My order arrived on schedule and was so easy to install. I will definitely be using 1Aauto for future needs and recommending to all my friends.

Perfect fit, works great, easy to install
These guys are doing Gods work. From the easy to understand website that tells exactly which model the part will fit on, to the awesome YouTube tutorial they put together. Sure you can find this part for a bit cheaper elsewhere online, but you dont have the certainty that its quality - and the fact that they took the time to make the tutorial in the first place is what made me want to buy directly from them. Probably saved a few hundred bucks doing this myself. And Im not very mechanically inclined
