2008 Ford Mustang Repair Question
Mileage: 71,000 miles.
Why is my a/c blowing cold only after the engine warms up?
Answer
have a pro take a pressure checkon the system to see if it is low first. Also if you are getting into a very hot car that has been baking in the sun open the windows up and drive it makes for better /easier on your a/c system. you may have an actuator problem as well, especially if it's vacuum operated and leaking vacuum. actuators direct flow of air and temp in heaterbox
Thank you, I will get a pressure check done and follow your advice on a/c start-up. It could be an actuator problem, because while taking my car on long trips (dallas to houston) the air pressure coming out of my vents decreases drastically over time but I can hear the blower motor under the dash blowing with no problem, it's just that the air seems like it's going somewhere else other than out of the vents, at that point, I just turn off the a/c system completely and give it a while to rest. Maybe one of the vacuum doors are not staying open inside the air flow compartment.
