You will get the required manual from the given link Home Toolsnyou https://toolsnyou.com

look on ebay

If both wipers are not working, then first of all check your fuses, if fuses are good follow wiper motor wires or look in owner's manual to find the wiper relay. Test relay with ohmmeter to see if it is good or just replace it.
Double check all wiring.
Last possible cause would be the a bad wiper switch which you can also test with an ohmmeter

Buy, ($20 at your local auto parts place) or flip through the Chilton Manual for your car, it will show you the exact steps.

Check your owners manual for the location of childproof locks. These are activated manualy and could have been engaged. Hope this helps
