It's been awhile since I spoke about this but basically I want to figure out how to undo whatever the mechanic did to stop the power lock switches and windows from working.

My window was going down automatically when I shutoff the car and I need an immediate fix and the mechanic somehow put the windows up and disabled power switches all together. I want to undo this and also check for condensation in the unit.

I looked at some schematics from here but I really need it in layman's term.

Help!?

Check fuses first. Then connectors & groundings.

...model is...?

...this might help regardless of ...http://www.cardomain.com/ride/748507/13

Its an 03 Maxima...

I looked at those particular schematics and it just a little too technical I guess.

I'll check all the fuses first then.

... and disabled power switches all together. ...?

The door sw panel should have a separate disable button. Check that first.

After going through your request and others suggestion, I can just suggest you please go through details in manual if you are facing still problem then concern technical person.
