A/C Condensate leak '85 300d Turbodiesel
 

Driver's side footwell is getting wet. I have removed the mats and see that there is water underneath the gray plastic padding attached to the floor.
Carpet on the sides of the footwell are dry.

Any help locating leak very much appreciated.

Here is your repair iso.
