I have a water leak right side front whether it is raining or when the a/c is on. The leak totally wets the carpet and bottom side of mat. When the a/c is on there is water hitting the ground on the outside. It there suppossed to be an elbow off the firewall? This vehicle does not have one, there is only the tube coming out of the firewall.

hi! run your a/c for halfhour and pull back your pass.front carpet and expose your lower evaporator case to see if water is leaking in that area.if so,it is possible your case drain line,which is located on the right side lower firewall in the engine compartment, with a hose mounted,pointed down.you must use compressed air to unclogg it.9 out 10 this your problem! try this first.if this is not your prob.check for a cracked case!

it sounds more like your heater core is leaking than anything else

Statistacally--most leaks come from sunroofs and yes they can be one side or the other. Happens from clogged drains. Sunroof drains run across the headliner and down the a-pillar. you can have them cleaned and checked. This is all assuming you have a sunroof. Hope I helped. Thanks.

sounds like the air conditioning drain for condensation is plugged

if you look on the engine side of the firewall you will see a rubber tube on the passenger side of the vehicle bent at a 90 degree angle that is the drain tube. very carefully try to insert something stiff into tube to see if it is blocked
