Default Water leakage? I guess

I have water dripping from what looks to be a drainage hose under the passenger side almost in line with the passenger side front wheel but further in. I'm not very mechanically inclined but usually a leak is bad. Granted it seems to be just water. No odor or color. The leak is coming from a hose that doesn't have anything connected to it. I dunno whether it was to something and was cut off at one point or its just leaking condensation. I live in Arizona so its really hot all the time. But its still leaking after a whole day. I'd think if it was condensation it would have stopped. Especially with the a/c being off for 24hours.

That is either the A/C drain line or the "dreaded water nipple".

There is a water nipple on the back of the cylinder head on the passenger side that plugs off an unused coolant water port. The rubber fails eventually and causes slow leakage.

If it is the hose coming out of the firewall, it is the A/C drain and is likely partially clogged and holding back some water that slowly makes it though as it sits. You can use compressed air or a short piece of coat hanger to open it up. Just be careful if you use a coat hanger not to poke very far or very hard because there are delicate aluminum pieces inside.

I figured it was the a/c, its about maybe an inch or two of rubber hose sticking out of the firewall. Just worried me because this is my first "newer" car. Used to my 1963 ford where pretty much a leak meant oil/coolant. lol. Never seen water drip. But yeah its water, No coolant in it at all. 100% crystal clear.
