When defrost is on it’s not defrosting now, smell coolant. It’s not overheating but there is a leak. Hopefully the video is okay.

the video didn't come through it takes a while on mobile can you try again? 9 times out of 10 it will be the heater core though it is not leaking enough to notice low levels it is enough to smell so we call it a seep. Start by disconnecting the battery and draining the engine coolant. Check out the images (below). Please let us know if you need anything else to get the problem fixed.
