A/C Randomly Blows Hot Air?!
I did a search but couldn't find this situation.
My a/c works great most of the time by blowing cold air and adjusting the tempature correctly as I set it. But if I drive for awhile it just all the sudden starts blowing heat not at a stop but a normal cruising speeds.
When it does this I switch to see what it is reading as the exterior tempature and it is always saying it is 30 deg. cooler then it is outside like its actually 97 but the tempature reading is 67.
Is this just a sensor or what? I am lost on where to start.
Thanks!

Mine was doing this a few weeks ago. Push the Auto button and recirclation buttons to do an electrical diagnostic on your AC system.
I'm currently throwing a code 14 which is the coolant temp sensor. But my AC is still working intermittantly.
