Once the truck's wipers are ready, the truck driver takes a break. Go back to Greg's house and open the blinds to get him away from the Video Games. When you go outside, Manny will drive by in the snowplow truck. Follow him left to the Laundromat.
He is the man next to the plowing truck.
you have to use it to divide the Wiper Fluid for the Snow Plow Driver
The wiper fluid is needed by the man operating the snowplow truck to the right of the school, so that he can see through his windshield to clear the snow.
Go the man by the truck near the school, got to your items and press use on the fluid. Then pour the correct amount.
you drink it
You go over to the snowplow guy by his truck by the school. Use the fluid by measuring it out.
You use the CD that you win playing Bingo with Grammie at Leisure Towers. This is late in the game and leads to the Wiper Fluid mini-game. (see the related solution or discussion)

You go to Fast Mart in the main area of Wimpy Wonderland, then use the CD. It will be inserted into a music box near the corner of the store. Click on the music box, and turn up the volume as high as you can go. Then you will see that some teens that were outside of the store are leaving. The store owner will thank you with some wiper fluid. ~Good luck! ;)
He only appears infrequently during the game, notably after you have the Classical CD from bingo and are going to use it at the Fast Mart's sound system. You need the dog dish from Rodrick's room before you can use the wiper fluid in the truck.
You use it for the dude that has snow on his window on his car and when you get the freezer fluid you will use it to help pour.
You don't really have a use for the address book on wimpy wonderland at all.
