I've seen video after video of a/c drain lines being blown out when moisture collects inside. I'd rather not waste time at a dealer on what should be a simple thing, but for the life of me, I don't see the line where everyone has videos and pictures of it. Was it changed for 21 and or 22? Looked center down in the firewall, looked under the driver side. Either I'm getting blind, or I'm just not seeing it in those locations. Would anyone please clue me in on what, or rather where, I'm missing here, please?
