Hello everyone, I have a problem with the AC of my 300 since i've got it 7 years ago, when i use the AC, yes it works, the water from the evaporator doesnt leave the car but flows on the floor from under the dash, i never could find the hose? that comes from the ac / heaterbox. Anyone knows where it goes? Thanks. Jack
There are two drain hoses which should exit basically under the middle of the firewall near the bottom as it curves around to become the floor pan. They may be plugged or the hoses (copper pipes actually) have been pulled off the heater box or aren't poking through the holes in the floor pan.
This picture should show you the two copper pipes with foam rubber gaskets around them near the back edge where you see a line of yellow insulation.
If you can see them when you're underneath the vehicle, carefully try to clean them out with a short length of coat hanger wire or a small pipe cleaning brush.
Thanks for that picture! But if i am correct the 2 copper pipes are above the gearbox? I'm putting it back on the lift tomorrow, i will have a very good look this time! Thanks again! Jack
