What do 'oa' and 'os' mean in this context?
As I get older I think a lot about the hereafter - I go into a room and then wonder what I'm here after.

Inside every old person is a young person wondering what the hell happened.

Could be a wiring fault, have a look where it goes between the body and tailgate to see if any are broken.

I guess oa and as might be off side so driver's side / right side with the a being a typing error since a is next to s on a keyboard. Only a guess but makes helping out harder if not understanding the problem.
