Ok, so I have a leak apparently in one of these two components I believe. I noticed just yesterday that the carpet underneath my passenger side front floor mat is damp and wet. Now typically I would say right away that this is the heater core that has a leak, however it does not smell of anti-freeze and my coolant level isn't low at all. So I started looking under the hood and realized that the evaporator core for the AC is mounted against the firewall, but it looks like the condenser box for the AC is between the firewall and the dash. (which is something new for me since my last two trucks had the condenser box viable and accessible from the engine compartment. So, I'm seeking some knowledge from someone that might have an idea of what is leaking. What I'm figuring is that if the condenser is behind the fire wall right behind the evaporator core, then there would not be room for the heater core right there, and that the heater core might be more towards the middle of the firewall. But, I could be wrong. So if anyone has some knowledge of this or has some ideas, please help me out. I'm trying to get an idea before I start opening things up and trying to see where it is coming from.
