Great product, works Great

### ⭐⭐⭐⭐⭐ Plug and play
*by A***R on August 19, 2025*

Worked perfectly

### ⭐⭐⭐⭐⭐ Exact Replacement!!
*by G***O on March 16, 2025*

These are the same brand as the OEM switches. They fit perfectly although I had to do a workaround as the keeper tabs on the frame had a couple break off. Not too tough of a job after watching a couple YouTube videos. I did fight with one wiring connection that I intimately left connected, and I just worked around the front panel. These saved me about $65.Thanks!!
