99 Tahoe 2 door water leak

[Pahtnah20]

I don't know much about engines, but when my truck is drivin and I turn it off, water tends to leak from a 3rd nozzle which looks like it is from my heater fan/core. (from behind my glove box) Can anyone help?

is was wondering if its in the cab or in the engine compartment. If its in the engine compartment i had a similar problem. Whenever i used my heat i would lose a bunch of antifreeze. It ended up being a little inline valve on the hose going into the heater core. That might be your same problem but you weren't too detailed. If its leakin in the cab, its probably the heater core itself.

Sorry for not being to detailed, but you pretty much nailed it! When I use my heater, I leak antifreeze. I had a friend check it and no prob since! Thanks for your help!
