Is this water or engine coolant? If it's water then the Air conditioning condensate drain may be plugged. Water can also enter if the body sealant has dried out where the firewall meets the body at the A post. If it's engine coolant then the heater core is leaking into the air box.

The rubber air tube that connects the air filter box to the engine is likely loose, grab it and check that is firmly attached both ends.
Also check the recall to replace the tube has been done: https://www.nissanusa.com/recalls-vin/#/#/Home

Reprogram what ? Basic electrical problem , not computer . Viewing electrical distribution diagrams an using a DMM - digital multi-meter to test electrical power flow is the way to diagnose . I would start at the main fusible links , fusible link holder . Free wiring diagrams here http://www.bbbind.com/free-tsb Enter vehicle info. year , make , model an engine . Under system click on electrical distribution ,then under subsystem click on power distribution . Click the search button ,then the blue link. Looking at the first diagram , i see the main fusible links . I would bet one of these is blown .

Does you car have express down, this means the windows will go down all the way as soon as you touch the window switch. To stop them from going all the way down just touch the switch a second time.

So did they clean the throttle body? It could be tps or iacv also. There are many things it could be. Is the check engine light on? If they reset the computer they should have seen what codes were present.

You need to test for power with a test light at the tail light bulb, If you have power it could be a bad bulb or ground. IF you do not have power then trace the circuit back to the light switch.
