In taking out the steering column and replaving it, the windshield wiper switch on the right hand side of the column fell apart. I have all the parts but we couldn't figure out how to put it back together again. I reattached it but it only works for a few wipes when I push it in to activate the washer. Does anyone know where I can get an assembly or can anyone explain how it goes back together? Thanks, Bob Hlavacek 10961
