I was on our way to visit our child plus I was looking at an 1100 mile ride. My partner had gone over the vehicle before he allowed me to take it. I had current brakes, an oil change, current windshield wipers plus tires. I also had a full reservoir for the windshield wiper fluid. I was about 400 miles into our trip when the weather began to be moderate plus humid. I reached over plus turned on the a/c, hoping to rid the vehicle of the humidity. I only had the temperature at seventy, so I didn’t expect it to be freezing in the car, although I did hope to be comfortable. The first half minute, it was really nice, however the further south I went, the worse the heat plus humidity got. My a/c couldn’t keep up with the change in temperature. I pulled over at a rest stop plus I called our partner. I told him I was going to find a hotel plus stop for the night. When he asked about the car, I asked him if he had thought to look at the Heating and Air Conditioning system. He said no plus wanted to know if I was having complications. I laughed plus told him that I will when it gets a bit warmer. I told him how the a/c wasn’t laboring unquestionably well. He said that I should pull over at the next maintenance station. He wanted me to have them fill the a/c with coolant. He had bought the coolant plus forgot to put it in the car.
