leaking air conditioning

Sounds like the evaporator. The evaporator in my 1994 Altima went bad and began to leak. I had it replaced by a mechanic for about $400 parts & labor. It requires taking the dashboard apart.

Good luck, Marc

the evaporator drain tube is plugged with debris, the evaporator needs to be removed and the crap cleared from the drain.

Neglecting to do so will cause damage to the ECM (main engine computer = BIG BUCKS) if it gets wet, which it will if you do not get the problem fixed.
