I opened the package. I tool out the plastic bag containing the replacement knobs. (I ordered two). I lined up the knob that needed replacing and pushed it on. The replacement knobs are of a better quality than the original and shouldn't break like the old ones. After this repair I was exhausted and took a nap.
The part was easy to remove and replace. Instructions were easy to understand. Once removed and replaced. The a/c worked great. I could control the temp and not be freezing all the time.
