How to remove prostar wiper motor

When I turn on the wiper the blades go up and stop on the windshield, have to push them back down. When I lift the wipers off the windshield they wipe about 4 times and stop on in the up position. I'm thinking it the motor.

How do you remove the motor?

I remove the main nut 13mm that holds the linkage, their's also about 3 t25 screws hold the motor to the bracket. I loosen them but the linkage still attached to the main bolt. What's the secret to remove it. It's a tight spot to work without removing the air filter box.

Thanks in advance for any help

 

I replaced the motor this morning, everything works good now. Their is a recall for the wiper motor on international prostar and lonestar 2007 to 2010. But I didn't have time and didn't want the dealer to hold on the the truck for days for a $130 repair. I brought the motor and install myself. Fairly easy job.
