Rear window switch in console / rear window washer

My rear window in my 2014 T4R Gen 5 can be operated with a key in the rear lockset on the door but the switch on the console doesn't do a thing. Like I said, window operates with key outside so know it has power.

How do you remove and/or test the switch on the center console? I don't see any videos on YouTube about it and am afraid that I would need to remove the whole center console to access it from below.

Any suggestions? (I know, just use the key in the rear door)! It would be nice to have the switch function.

ALSO, rear wiper works fine but the rear window washer doesn't spray at all. Could the spray jet be clogged? Does it use the same reservoir as the front? I don't see any mention of a second reservoir in the manual so assume not there. Manual says if the spray jet is clogged it should go to dealer, but that seems extreme to clear the jet. Any experience with this? Recommendations appreciated.

Thank you!
