- I was sitting in my car while it was off and i spotted a VERY small drop of coolant leaking from somewhere(?) under my dash onto my carpet.
- Where is this leak coming from??... and why??

 

Sounds like it'd be comming from your heater box..... thats the only thing under the dash that has coolant going to it. The hoses might have come semi-loose, or you're heater core is out. Good luck figuring it out.

 

It's either a leaking heater core or possibly the connection to the heater hoses.

 

Yup, and here's how you fix it. Do it now before it rusts your floor.
