May Car Part
I can'tbegin to tell you how pleased I am with the staff at 1aauto. I needed to get my A.C. switches to work since only #4 switch was working..
They not only expedited sending my part but found their installation video so so helpful so easy even a 65 year old lady like me could install it.
Mahalo 1aauto. I will definitely order parts as I need them from your company and awesome courteous staff!
Aloha from Hawaii!

Saved Money with Easy to Install Part
The installation video for the part was clear and concise. It took about 15 min total to install the resistor. The price was about a third of the dealer's price. Shipping to Canada is about $40 but still worth it to save about $100. Estimated delivery time was accurate.
