Customers may complain of A/C water leakage onto the driver side floor. The leakage may be more noticeable after the air conditioner or front defogger has been operated.
This condition may be caused by drain tube blockage, or the heater unit not being properly sealed to the bulkhead. The bulkhead silencer pad may be positioned between the evaporator foam pad and the firewall, causing an improper seal. This could cause the evaporator drain tube foam to become deformed and allow water to drain onto the floor.
To eliminate this condition, first check for drain tube blockage. If no blockage is found, install a new evaporator foam pad as described in this bulletin. Also, inspect the heater assembly for cracks or other damage that could cause leakage. If cracks or other damage are observed, replace the heater assembly.
it leaking on the passenger side but i also look on the driver side but i still can't find that line
Did you check under the hood by the drive side and try to find the drain tube.
