82 300SD

background: Left side would flash quickly, but front and back lamps functional. Right side would flash normally, but only when I moved the stalk partway. If I moved it all the way to detent, right signals don't flash.

Current: Both sides now only provide solid on (no blink), right side still only illuminates when moving stalk part way.

I suspect it's the combo-switch from the threads I've searched. Is the method get to it to remove the steering wheel?

Thanks
