95 Corisca Wiper Control

Looking to find out if I can get an intermittent (delay-able) wiper control swicth. I only have two settings on my 95 2.2 Corsica.

Anyone know if they make a compatible unit in previous or later years I could find at a junker ?

Thanks
Ray

I have a 88' Corsica, and I have the same problem!! It's either on low speed or high speed.... I hate it! I would also like to know if there is something that can be done to change this.
