Q: AC problem

asked by on June 13, 2017

I have a 2007 Mazda 6. My AC is only working in the morning and at night when the car is cool. I want to recharge the AC system. When I check the pressure of the low service port in the morning (when it is cool outside) the PSI is around 25, but when I check the pressure in the afternoon (when it is hot out) the PSI shows around 60 PSI. Should I recharge my car AC in the morning when the temperature is cooler? In the morning when I drive to work the AC works perfectly the whole time. It also works perfectly at night once its cooled down and runs the whole time, but during the day (10am,-5pm) it only blows cold air about 25% of the time. Any advice on what I should do?

I look forward to hearing back from you. Thanks for your help!
