Where is the ac evap drain line on 2010 Ram Dakota?

for sure all generic answers here are wrong. for all grand Cherokees. 93 to 2010
posters jeep is 2001 WJ , only WJ 1999- to 2004 (USA only) are correct. RHD cars are not the same. UK

we all know why, (clogs happen evap drain clogged)
we all know it must be cleaned. (just like clogged kitchen drain )_
what is not told , "your hands can not reach the spot. transmission block you, and CATs)
the drain tube on my 2008 wrangler(2dr) is in plane site just above starter. so is easy
the wJ and WK jeeps are not easy, and WK is the hardest of all made. blocking shield under car.(above right side of transmission NAG1.

THE FSM LIEs IS HERE. Jeep sells the cleaner kit and the TSB covers how in 24 long pages.
but step 1 below fails; (way to go JEEP,. FCA) #2 is CAT crossover,3.7L

You need to find the drain pan line that comes through the firewall. Open the hood and search for the line on the passenger side firewall. The line is probably clogged from insects, animals, or other gunk. use a short piece of dowel or wire to unclog the line and allow the pan to drain to the outside of the vehicle.

Either one of two things has happened. The heater core is leaking or the evaporator case drain tube is clogged or disconnected. If the evap case is clogged then clean out drain tube using compressed air or a water hose. Do it in short bursts either way. If its heater core removal of dash is necessary.

It will be on the bottom of the AC Core Housing and run to the Firewall and the Passenger side of the Console.

Sounds like the drain hose is clogged up. Open hood and on the firewall on the bottom look for a rubber hose about an inch or two long sticking out of the firewall blow a short burts of air into it and the debris should come out

should be on the fire wall on the right hand side near were the ac lines go through.

its not the ac its a leaking heater core

There is always drain tube because AC always condenses water.
The drain tube must have become disconnected. Look underneath the car and you will see it pointing down.

actually the drain is clogged it somewhat accessible on the firewall behind the engine . the water fills upthe evaporator box and when you go around a corner it dumps on the floor if you remove the drain spout you blow some compressed air in the hole to clear it if it continues you may have to remove the evap and manually clean out the box .

the ac drain is more than likley stopped up, they tend to get clogged with debri not allowing the condensation from the evap. core to drain properly, thus allowing it to leak into the floorboard.
