Switch was perfect
Switch went right in everything works except the driver window which was where my problem originated. It goes down then right back up which has led me deeper into the abyss, but I at least have gotten it moving

My 1st Purchase
This was my first online purchase all through youtubing how to fix my switch. I was super excited that I installed it myself, as a single mom on a budget, this purchase, price and video install was PERFECT for me! Although it didnt come as fast as I like, I saved some dollars!

Working ready
I got my part in just four days and it worked just fine. Went in just like the video said it would. Very nice fit and it worked well. Five stars compared to the last time this happened. Last time this installation cost me almost $150.00.... Good for 1A Auto....

Good part, easy installation
Helpful online support. I agree with online sales, always best to call and verify part. Mine had possible confusion regarding application to my Nissan model. The video was pretty clear. Install took all of 10 minutes max. Saved min $150.00 vs. job quoted by my typically fair priced mechanic. Paid for my camping trip in the woods over Thanksgiving. Part works fine but only installed for 2 weeks. Lifetime warranty. My mechanic had only one year warranty which is a good one.

Some of the switches are a little stiff but not horrible so. Otherwise is a good product. No complaints so far.
