I bought a used 2013 Expedition. Other than a few miles and 2 owners it looks brand new. The A/C is giving me a few problems. I took it to my trusted mechanic. He is not sure what it is. When I turn on the A/C it blows cold. When I turn on the rear button it gets hot in the vehicle. Like there is a switch out or it is freezing up. Anyone dealt with this or know where to look? I am going back on Thursday.

Welcome to the site.

He/she needs to check the system to see if the compressor is turning off when the rear is turned on. You should also check the pressures on the system while it is in there. Also check blend door operation to make sure the rear unit isn't dumping heat into the cabin.
