  I think you pretty much have everything that is available. If you run in to issues just ask here and someone will be able to help you out. I do not think you will have any issues with the windshield wiper motor. I like the fact that you can run two of them together and just use code for one with a quick pause after the first one starts to kick in the second one. I am running a couple 12V 7 Amp pump motors and they work great. I have some code I wrote to test them using a couple of push buttons. I will be happy to post it if you like.

  Thanks NWCCTV
  I would appreciate looking over your simple testing code.
  The concern I have, which I will confirm as soon as my HB25 arrives is that there is no good information available
  concerning the exact construction of these wiper motors. I'm thinking they will work out, but I will need to bypass the
  Wiper motor control board. I have a plan for the wiper control board bypass test circuit.
  I'll be confirming operation of the HB25 controller on a small brushed motor that I use for testing before connecting my
  1998 Chevy Tahoe wiper motors to the HB25.

  OK. Let me dig up the code and I will post it here. Also, are you aware that you need an HB-25 for each motor? I originally thought that one would work for 2 motors because of the way it is worded. However, I soon found out that was not the case. You can control 2 motors simultaneously with two controllers.
  
  Edit: Here's the code. Let me know if you need further assistance. I think I have a slimmed down version of this also but I am not sure where I put it. This works great for testing one or two motors though.

  Thanks
  The code will be helpful.
  I do realize that I will need two HB25s to control two motors individually, However
  as a part of my test, I think I'll end up connecting both of my wiper motors to one controller, just to see how much speed
  variation I get on two motors connected in parallel.
  Since my new platform will be driven using differential drive with two motors running in opposite directions, It will be
  very interesting to see the result.
  If my tests work out the way I'm expecting, I'll keep checking the clasifieds section for when I'll be needing another HB25.
  Sometimes these experiments take quite a bit of time because, once in a while, Life gets in the way.
