I am having a problem with the washer motor
That stays on no matter what ...
You need a new wiper motor cover. Not the whole motor, just the cover. The cover has a circuit board inside it that gets condensation in it and ends up doing what it's doing to you. Go to the gmonlineparts store. They are the cheapest.

Oddly enough, here in the UK, our wipers are on the other side than yours and so too is the master cylinder.
Our CTS's here had a recall on the master cylinder, as it was prone to getting waterlogged and go rusty, so we had a plastic one fitted.
Looks like that particular spot is a water hazard.
I recently had this same problem. I was quoted $200-$450 for the part from dealers and auto shops plus labor. Ended up purchasing just the motor from Rockauto online for about $60 and took me about 25 minutes to replace. Works like a charm and haven't had a problem since. There is a youtube video detailing the replacement process. Search for '2003 Cadillac CTS wiper motor removal'. I found it to be a very easy fix. Good luck.
