the A/C in the 2011 transit connect quit working. I brought it by my mechanic and he checked it out. after three days of working on this and doing research on the vehicle, he told me that there is no reason why it should not be working. He told me that I would need to bring it to the dealer and have them check it. He had meantioned that the A/c system could be controled by the computer. He checked all relays, fuses, pressure in the system and all checks good. Is there any chance that the computer in the van controls the A/C in any way?
