Water leaking in glove box? looks like there is a hose that comes into the box... water is dripping from that hose under the near the back of the engine .

It sure sounds like the heater core, especially if you have water leaking inside the cabin. The two heater hoses only go from the engine to the firewall, and do not go into or through the firewall. They connect to the heater core right at the firewall.
Check carefully around the back side of the engine and the heater hoses, though. If a freeze plug is leaking, water will be dripping off the bottom of the engine. If it is leaking before the firewall, that would not be the heater core.

The drain on your evaporator core housing is most likely plugged. Condensation on the evaporator core drips down into the plastic housing and drips onto the ground through a hose on the firewall on the
passenger side.

Find the small hose on the firewall in the engine compartment. You should be able to pull off that
hose and see if its stopped up. If the hose is ok, you may need to remove some of the ac ducts
under the dash to get to the evaporator core housing to unclog the drain hole.

I have no doubt that thats the problem.

The HVAC drain is stopped up and needs to be cleaned.

THE BLOWER MOTOR RESISTOR FAULTY IF YOU HAVE ONLY 1 FAN SPEED ALSO AC AND HTR CONTROL SWITCH BAD.WATER LEAK UNDER GLOVE BOX COULD BE THE HEATER CORE LEAKING IF LEAKING ALL THE TIME WHEN THERE IS NO RAIN.

what kind of fluid is comming out is it antifreeze or water is it from the air conditioner if its water the its a heater gasket. If its only rain water when it rains lift up carpet and look for it ,send back message let me know

It is either water from the a/c drain hose, which, if leaking inside the car is plugged up, and must be cleared (from under the car, the tube is in front of the the passenger area, roughly behind the front tire, near where the passengers feet would be. Use a thin wire to dislodge junk in the tube.
Or it is your heater core leaking, which means it needs to be replaced (you can determine if it's this if the 'water' is antifreeze, by checking the color, and the odor-anitfreeze has a sweet smell.)

The evaporator drain might be clogged. Get under the truck or open the hood and look for a rubber nipple coming out of the firewall on the passengers side. Try sticking something in this hole to release whatever might be stuck in there, usually leaves or sediment. Be careful, don't go crazy pocking something in there. The evaporator core might be near the drain hole, you don't want to poke a hole in it.

check the smell of the liquid. if it smells like anti freeze...heater core is leaking. no smell and it could be moisture from the a/c evaporator core (condensation like on a cold soda can) or the windshield seal is leaking.

They are not always easy to see and they differ in length but yes they are typically on the passenger side firewall and may extend down towards the lower firewall or just drop out an inch from the firewall. a coat hanger is not always going to work and you will need to be careful not to put a hole in the evaporator that sits just inside from where that drain comes out. it is possible that the lower cover where the condensation is collected has a crack and may not be pluged at all. look above where it drips on the floor and see if there is any sign of damage to that cover. You may find that it is easier to take off the cover and clean. that will just depend on your confidence in dismanteling that part of the dash and heater box.

Did you ever get this fixed? I have the same issue! Thanks.
