Today I found a lake on the passenger side floor.
I think to have found the cause.
For me is the A/C lower evaporator drainage.
I have blown on the drainage water exit tube to clean it.
Now water drops out well (in the last month I have not watched if the water drops out)
I need an advice.
For you i need to extend the short evaporator drainage tube with a long tube (so the water drops far to the passenger floor) ???
I need an help
Thank You !

 

making the drain longer or cleaner does work if thats your problem. We have fixed a few that was as well
