A high current relay should help-but, before going that route, check your linkage for binding, make sure its greased/not binding. I've done the wiper motor relay mod on my trucks and gbodies to speed the motors up. This sidesteps the protection that the stock fuse provides though so you'd want to add a fuse before the relay to the wiper motor.
