Fan control
My fan speed control started acting up not wanting to engage the blower at all. Locally only could find entire h vac control panel. Didnt need whole thing luckily 1a auto had just the part that was broken easy install after watching their video. Saved me ton of money and works like new again! Very happy with the purchase.

You get what you pay for.
The switch fit was decent. The detents are vague and it actually only seems to have three speeds rather than four.

Works like a Charm!
Pretty darn easy to change out, just finicky wire terminals. the switch works great and you do not have to change out the entire control panel.

Perfect replacement
I was going to have to replace the whole panel of switches. But worth a little research I found the fan switch on 1aauto. The part was a perfect replacement and for a fraction the cost of relaxing the whole panel.
