Driving to work 2 weeks ago while running AC white smoke starting coming into the car thru the AC Vents so I turned off the AC and got Car to my mechanic. He said a hose had came off and most of the antifreeze fluid had leaked out so he reconnected hose and filled antifreeze. When I picked up car it seemed fine till about 15 minutes into driving then I smelled a faint burning smell. I can't afford to be without a car again for another week or two so I decided to just not run the AC because I definitely feel the issue or what ever caused the issue is not revolved.Today it started raining while I driving home and my windshield got foggy as if something were steaming under my hood so when I got home I check under the hood and saw something leaking from under the power distribution box and dripping on something else which was causing a little smoke. I know nothing about cars but can someone please give me an idea of what's possibly going on with my Car? I have a picture but don't see how to attach it.
