Need help fixing windshield wiper!! (1987 Nissan 200SX)
 

I don't really know anything about cars, but on my mom's car, which's a 1987 Nissan 200SX, the right side windshield wiper doesn't work, but the left one does. My mom thinks it's a broken wire, which was chewed by a mouse.. she thinks this 'cause someone else looked under the hood and found a wire chewed, and because she saw a mouse in'er hood before.

So, if this 'is' the case.. then I might just have to fix the broken wire. So....can anyone tell me where I can find the wires for the windshield wipers?? A general location is fine, if that's all you know. (A general location as in "when looking under the hood, it's in the far back left, near the bottom"... 'cause I dont know anything about cars, so I wont know where it is if you tell me it's by the so and so and whatever). But if you know exactly where they can be found, that'd be great.

Thanks a lot! :)
