    My vote is for the HVAC housing to firewall seal as mentioned. Second suspected area could be clogged condensate drain.

    ^^ Yep.....that A/C housing seal has given me the same trouble on 2 Caddies and my wife's 81 Cutlass wagon. I can''t imagine why GM did such a crap job of sealing that gigantic hole. So......I'm with Ape Man on that one.

    Cheers.........R.

    Well in your case it was the 80's. The decade where American auto makers wanted to show the world how crappy and cheaply an automobile could actually be made. So they used the worst materials, the worst assembly methods and the worst labor they could find.

    And there you have American cars made in the 80's

    "EDIT: Ok I was just investigating the heater box. Now we're talking about the entire assembly that takes up about the whole passenger side of the firewall correct?" Not really. The first bad leaker I had was my 81 SDV from Sarant Cadillac in New York. Nice car but lots of probs to take care of. I too noticed the water on the passenger's floor. Towels were used for the first few weeks of this annoyance. Then anti freeze was added to the mix which had me thinking crusher .......... I gave in and had my rad shop replace the heater core. In doing so, he re-sealed the top cover on the engine room side of the A/C box and when he was done, all leaks vanished. Maybe I got lucky but maybe the top part is the problem.

    Cheers.......R.

    OK so the car has now survived 2 days of torrential downpour while sitting in the driveway. I intentionally didn't drive the car during his time because I want to be able to draw conclusions.

    After a TON of rain the floor and the underside of the heater box is dry. Bone dry.

    So, I'm not sure if that proves anything 100% but where is the AC drain on these? What needs to come apart to check it for clogs

    The drain is a hole on the underside of the heater/evap. box on the firewall. It's easy to see from the underside of the car. There is no hose on the drain hole. I t is a big chore to remove the top half of the cover. I just removed mine and cleaned all the factory caulking and re-caulked with no leaks.
