Thx Ron that helps. Do you have a view of the dash area that shows location of the core housing? Do I have to take any part of the dash or glovebox out to get to the area?

The AC/heater plenum is right behind and under the right side of the dash panel and beside the thing listed in the steps there is nothing else that needs to be removed. The heater plenum has the access panel shown in step #6.

The link isn't working. Sorry been delayed addressing this. Here is where the leak is coming from. I tried unplugging the drain, water comes out of it, but still is leaking into the truck from the spot i'm pointing to in the picture. Or n ot it won't let me add pictures for some reason.

Can you post the picture ?

Is this water or coolant coming from the leak?

can you repost that link too when you have time ?

Okay then that is likely water from the condenser drain, the drain should come off the back of the AC/heater plenum and go through the firewall to the out side at the bottom of the plenum. I can and if your going to need to remover the Plenum and heater core you will need to remove the instrument panel. I have enclosed the steps to do both in the link below. Be sure to print them out as they do expire over time. Please take a moment to rate my service so I can get credit for my time, the question remains open for follow up even after doing so, all you need to do is return to this question if need be.

Thank you again.
