Windshield wipers wont stop mazda protege1995

I have a 1995 Mazda protege and the windshield wipers didn’t work when I got it. I changed the motor and I noticed the fuse was blown, I changed that too. The wipers work all the time now at full speed no mater on what setting or speed I turn them on, even in the off position and the fuse keeps frying and I have to replace it every time. Any suggestions at all would be appreciated. Thank you

There seems to be a problem with the switch or in the wiring between the switch and the motor.

Any idea on how to find out what is it the switch or the wiring?
