I have water leaking onto my passenger floorboard after I run the AC for a while.
*
I have contacted a dealership service department to try and resolve this problem, but I have not been able to do it yet.
*
The dealer gave me a quick fix method and quoted me 4+ hours to have a technician actually pull apart the dash to unclog the condensation line. I followed the dealer's instructions, but the problem was not fixed. It seemed that the condensation line was not clogged at all.
*
I think there might be a linkage that is not connected behind the firewall so the water is running out the linkage and following the pipe back inside the vehicle.
*
This is a Grand Cherokee Laredo and I have not found a chilton manual that will show the dissasembly of the dash to fix it myself.
*
I was thinking I could punch a hole in the floorboard and create a drain myself. If anyone has come across this problem, please give feedback.
*
THANKS

Just to verify about the drain. I know you said it wasn't plugged but it was worth writing.

This drain is hard to find, it empties into the frame rail below the pass. Floor. You can pull the blower motor out to see if the box has water. The drain is inside the frame, the way to unstop it is drill a small hole in evap box by the floor board. Find a small long wire and poke it out, im you have a mig welder that wire works great. Get a long piece and fold it over and poke it down the hole in the bottom.

Water leakage DEFINITLY does not happen after rain? If it does, I would look closely at the windsheild and A-pillar, Perhaps the metal has a hole behind a leaking windshield seal. Water would then run down the A-pillar into the floorboard area.
