i blew the dust off of some manuals :-)
it looks like the book time is about an hour. to me that means that you don't have to tear down the column too far to replace the switch. you will need a puller for the wheel and possibly to remove the lock plate that keeps the wheel from turning when locked. i strongly suggest a service manual!
if you head in this direction, try plugging the new switch in before tearing down the column. if the problem is NOT the switch, you will have saved the time opening the column :-)
the first thing to test is for power coming out of the switch at the column plug. you should easily find the lead for the side that works. the non working side will take longer ;-)
