Does anyone know if it is possible to replace the right knob potentiometer On the 2009 Bose system?

The right potentiometer is only registering in 2 positions. I tried spraying electronic contact cleaner into the knob to try and potentially clean the wipers in case it was dirty contacts but no change. I can't tell if the cleaner even made it to the wipers and contacts.

Everything else works normally.
