I just got a 2012 Taurus SEL with 68K. I took it on a 500 mile trip. It was hot today and I put the A/C on. It works but it blows slightly warmer on the driver's side. Both knobs are all the way on cold. A/C is on with recirculation and fan on high. It switched itself off when I went to pull away. It did this about 4 times (maybe the A/C needs recharged and this is a self protect feature?) I replaced the cabin air filter and nothing. I'm leaving to go back home Sunday. It's another 500 miles and it's going to be about 93. What's the issue here?
