I recently bought a 2010 jk mountain edition with the description on the vehicle saying it is equipped with a/c. Being -50 Celsius, i didn't bother to check for the a/c button. a week after i see that there is no button. After reading some threads, i've come to learn that as long as there are some sort of wires, it would have a/c. can someone please verify if i do or do not?
