The AC is blowing hot air
Hi there. The most common cause of your truck to suddenly stop blowing cold air is low refrigerant in the system. In some cases, it may just need some refrigerant added to its system. It is best to install a manifold gauge set to check the pressures in the system. If there is no pressure at all, then it may have a major leak. If it has plenty of refrigerant and will not turn on, then it may be a bad pressure switch or another electrical issue. I would enlist the help of a certified mechanic, Like one from YourMechanic, to inspect the AC system and replace any damaged or failing parts.
