I had to get my 2008 V6 Mustang jumped a few times yesterday, so I cleaned my battery and connections and it still didn't want to start. I pulled the battery out and went to Autozone to have them test it. Turns out I had a dead cell in the manufacturer battery to I had to replace it. With the new battery in my car fired right up so I took it for a drive and noticed my A/C is no longer blowing out cold air. Any suggestions on how to solve this problem? I also had a "Tire Pressure Monitor System Fault" appear on my dash, but I checked my air pressure and after about a minute of driving that turned off. So now the A/C is main concern. Thanks in advance for any helpful suggestions.
