"Here is the wall wart type power supply I use to power my wiper motors (herbach.com #Q5980 $7.50). The key feature is that you can vary the voltage which varies the speed of the motor. I just cut off the plug on the end and wire direclty to the wiper motor as you show on your site."

"As you can see they are inexpensive but you do have to pay shipping."

"Wal-Mart carries a number of different models ranging in cost from $12 to $16. The key difference is the amp maximum. The cheaper ones are limited to 300mA or so and the slightly more costly ones do up to about 1.2A. Well worth the few dollars. "

"These can sometimes be found for as cheap as 25 cents at yard sales or thrift stores."

Thanks for the adivce Propmaster!
