Q: No cold air coming from AC

Hi. If the system doesn’t see enough pressure, it won’t turn on. If the AC is charged to specification and it still doesn’t turn on, it’s probably going to be a switch in either the AC circuit or the control side for the blend doors inside the dash. If you need further assistance, I recommend you have a mechanic, like one from YourMechanic, inspect the AC to make sure everything is in working order.
