Thanks to Northof49 and conboss I was able to get the switch replaced. Just as reported the rear of the center console comes apart with some firm pressure. The video link in the HFL fix thread was helpful. Once I got the rear of the console separated I disconnected the electrical wire clips. Five screws secured the rear heater control panel. I was able to get that out and then found the switch was secured by two screws. Replacing the switch and reattaching the rear of the console went smoothly.
BTW, Mike Hale Acura service told me that it would cost approximately $300 in labor to replace the switch. They either didn’t know what they were talking about or they intentionally misled me.
