Where is this leaking from...?

Occasionally I've noticed a small leak on the ground after driving and being parked for a while (mainly like after I get to work, etc.) I've checked all the fluids over and over and everything is normal, but this still bugs me. I find the drips on the passenger side right behind the front tire (see pics below) The only thing I can think of is that maybe its coming from this hose coming out of the firewall (see pic with red arrow). If so, is this some type of release valve from A/C or heater condensation?
Thanks for your input

 

Thats your A/C bud. Normal.

 

A/C drain

Perfect, thank you guys

 

I am compelled to touch and smell every new fluid below my vehicles or my friends/family's vehicles. You can quickly and confidently tell if something is oil v water v coolant. I have been fooled by water many times but no harm in checking!

 

I've done that too and thats why I'm kind of confused because I knew it wasnt oil

 

Just taste the fluids...
Its Friday right?

 

Smart to direct that drip away from the frame.

 

Confirmed, your truck is male.

Thanks for posting the a/c mod to OP. That was one of my 1st DIY projects. Huge thanks to the community as a whole for these tips!

 

Taste it ...

 

Yup a/c drain. Simple mod on here already in the thread sub 10min. Works great.

 

Better get a bucket and a mop for this wet ass....

 

Ahh so it must be spit...cause god knows I can’t get one of those wet without it

 

Don’t forget the macoroni in the pot...

 

Wet ass puddle right guys?
