After I fixed my issue with the A/C stuck in the defrost mode
   • 1998 Dodge Ram 1500 AC stuck on defrost  
My A/C was not cooling and I discovered my A/C clutch would not kick in. After research I learned that I needed to recharge the system, which it needed pressure in order for the A/C clutch to kick in. Once I recharged the system I had cool air again.
