i havea continual leak coming out of the drain on the firewall. what is the reason for leaking since i bypassed the heater core hoses please tell me what it is causing it and how to change it
the evaporator drain comes out of the firewall and when the a/c is on it is normal for water to come out of the drain. since you didn't specify as to what type of fluid is leaking. I will assume it is H20 and you don't have a problem at all.
