72 duster wiper switch

Just got rebuilt my 2 speed wiper motor and have it installed back in the car. The thing now is that when I turn on the wipers they make only one turn, after that they dont work anymore. After this happens, there is a clicking sound that comes out of the wiper switch that moves the alternator gauge down and up. If I disconnect the wiper switch the click sound is over. but I still have no wipers. Does anyone know what should I check in the car too see what is wrong?
