If you have time , I would go to the junkyard. I found all the switches that I need,including the coveted power seat switches . I would at least give it a shot , heck of a lot less expensive than a new fader switch.
The stealership wanted $43.00. for a window switch , went to the yard' and got one for $5.00 . still works too. Some of these parts can be found on the Peachtree website also.
Happy hunting.. It's sweet that the orig. Becker unit still works ..
