Use the search feature on this site - lots of pointers for repair of DC07s.... However... What makes you think it's the motor? Motors usually work, or they don't work, or they work badly - they seldom stop working then start working again - that's a symptom of a poor connection - wall socket - plug - cable - switch - internal wiring - connections to the motor. These are all more likely causes and much cheaper to fix.
Good luck...
