hey all. i need help plzzzzzz. i'm desperately looking for a complete wiring schematic/ diagram for my maxima. think i'm sitting with a short somewhere as both electrical fans start when i start the car and doesn't stop till i switch off. also the electrical windows wind up and down on their own free will (not nice as it is winter here lol). any help would really be appreciated. oh yeah, it's a 1994 model

Once you have the FSM have a look see at the ETS (engine temp sensor) and its wiring/connections - when they fail the ECU decides to switch the fans on permanently so as to prevent overheating in the absence of a proper ETS signal

 

Greeny and LvR, big cudos to ya. the help was awesome

 

As LvR said, the first place to look on the fan issue is the engine temp sensor or its connector. It's a common failure point and will cause the fans to stay on all the time as well as make the car run really rich, hurting efficiency and power.

The windows are usually a problem with the master window switch in your drivers side door. you can take them apart and attempt to clean the connections, but you may find it easier to just replace the switch assembly with a salvage part or one from the dealer. however, they're about $250US last time I heard price on one- not cheap! You can usually get them from salvage yards for under $50US, but they often have the same problem as yours.

That said, I have one or two in my garage at home that I don't plan on using. I bought them cheap as spares for my car, but no longer drive mine daily and don't plan to need it. If you need it, I can send it to you for $20US plus shipping cost. (Since you said it's winter, you're obviously not in the states...)
Let us know if you need some parts, as someone here is usually willing to ship international.
