Leaking coolent from evaporator drain

[macker123]

I was driving up a mountain a few days ago and heard a loud "POP" when I was really pushing the car. I thought it was a hose, but after inspection I could not find anything wrong, but my car's temperature gauge is always on the cool side now instead of in the center like usual.

I am now leeking fluid out of my evaporator housing drain, about 1 drip every 3-4 seconds. My temperature gauge is also stating that my car is running excessively cool, which is not possible.

Can somebody PLEASE help me what is wrong, I have a feeling it is either my heater core or in that area.

Please help as I have the next two days off, so I would like to get it done on my days off.

Thanks
