I've got a motorhome that sits a lot and the dimmer quits on it. I do a bunch of hi to low clicks with the lights on, and it starts working after a while.
I've also seen where a switch gets wet or there is a poor connection at the plug on it and the dimmer switch plug burns, melting it away. there is no fuse other than a fuseable link on this circut so it can get very hot.
At least pull back the mat and take a good look at the plug. Look for signs of moisture (rust) there too.
The older I get, the faster I was!
