Got a flash rain storm, inch of rain fell the other day and the LeSabre was setting out side. Right side carpet was wet, think it came thru the heater system. I have used the power washer and not had any leaking windows from that. So how do I find the heater duct drain, I seem to remember seeing a little hose hanging from a heater duct once? I removed the leaf screen and felt all around also where i could reach on the outside & felt nothing. Thought I would ask here before I pull the fan out and feel all around in there. Thanks Al. Al
