The switches don't stay down when pushed. They are momentary switches.
It's possible that just the lights are burnt out.
Now if the rear defrost isn't working... that would be easily noticable by frost not being defrosted. Have you checked the electrical connections going to the defroster grid on the window?
The defrost might be the connector...it did not defrost the snow tonight...I'll check it better tomorrow.
As for the the OD switch, yes I have pressed it while driving....no difference, speed up or slow down of rpm's.
