Air was working fine on express way all of the sudden it stopped blowing cold

Hello, If the compressor can be heard cycling at a normal rate, I would be concerned about the blend doors. Check to see if the rear A/C gets cold, and if it does, you know the problem is even more likely a blend door. If the rear A/C is warm as well, you likely have a clogged orifice tube, or another A/C refrigerant system issue. Having this diagnosed will likely include testing the blend door actuator with a scan tool which can command the actuator to open/close. Finally, the controller may be bad as well, so when you adjust the controller to lower the temperature, it may not be sending the message to move the blend door.
