Having problems with your 2001 Mitsubishi Montero ?
Why does water leak inside the passenger side of my 2001 mitsubishi montero from my air conditioner?
Your a/c evaporator drain is stopped up or blocked off can be seen at firewall area on passenger side looks like a short black hose coming out of firewall and turns down with nothing hooked to it if this gets restricted the blackbox under your dash fills with water and eventually leaks in floor you can try and run small piece of wire up hose to unstop but be careful not to punchure evaporator core
