replaced fuse for radio and got my OD light to work but no change in my wipers got to checking and the wiper modual is telling the moter to keep running like the relay in it is fubared.

 

it seemed to me like the CTM sent a one second dc pulse to the wiper relay in the pdc, which in turn made a tick (on) and then a tock (off) sound, as it opened and closed the relay. this in turn kicked on the wiper motor for a second, and the park circuit on the wiper motor brought the wiper arms back down to the home position.

all i can suggest is trace your electrical signals with a voltage meter, including the signals to the CTM from the wiper switch on the column. i've got that all documented up in those other posts.
