I replaced a faulty turn signal switch (87 GN) and in ther interim, I have somehow damaged the windshield wiper switch within the column. The stalk goes back in, but switch will not turn...and the wipers run constantly. I replaced the stalk with a new one, but same result. I'm assuming I need to replace the switch within the column. Anyone have any tips or hints on this.....or better yet....where to get a new switch assbly? 
TIA
