Answers :

I would pull the motor assembly again and cycle the wipers by hand to get the blade assembly back to park horizontal position then re install. This is common when replacing the motor that the nylon gear assembly in the motor was not in horizontal park position
Try adding a ground wire, just take a wire and rub it on the motor ad the other end to ground on battery. i find alot off problems are caused by bad body grounds or on gm wiper motors the internal ground goes bad. grounds are one of the biggest problems in electrical systems on all trucks and cars.
