Climate control, knob, backlight blink off and on

[JohnUSA]

2009, Two knob climate control module, with backlighted knobs.
The backlight on the right side knob has started randomly blinking off and on.


How are they lighted? Do the knobs pull off? Have to go in from the back?
Thanks.

According to the service manual, they state replacement.

"The A/C-heater control cannot be adjusted or repaired and must be replaced if inoperative or damaged"

Wow, many thanks. Well, that's permission to disassemble as far as I'm concerned. We'll see what happens.

Separate, but related observation...I just discovered this control module is from a 2011/12 RAM, and I have a 2009 RAM.
I pulled it out to see if I could take it apart, and there is a 2015 date on it. So, prior owner was down this road before.
