Hi, the outside temperature is 87 degree, I been running the air conditioning for hours. When I park the car in the garage and I saw there is some liquid, touched it and it is not coolant or oil, feel like water, no smells. The water is coming from a little tube on the passenger side of the car need the firewall. Could this be normal with the temperature that high and also running the ac for hour? What do you think this liquid is? And what is the little tube from the passenger side?
