100% Satisfied
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 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! It's nice to have all functions back again - auto up/down and child locks - like a new car!!

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 90's, it was still very helpful

the entire process took less than 30 minutes with no surprises.
