Q: Air conditioner doesn't blow cold air

asked by on July 26, 2016

It is summertime and over 100 degrees where we live. The A/C has stopped blowing cold air and just feels like vent air! We recharged the coolant, but it was over charged, so we let some out and then added some back in. That didn’t help. The auto repair shop said the expansion valve was malfunctioning and needed replacing. After the replacement, it was just barely better, but not cold enough. He told us there’s nothing wrong with it. But the car does not cool off! I asked him how can we get the air to come out cold from the start. The air just does not get cold in the daytime - at night it does, but not in the heat of day. How can this be fixed?
