AC Hardly Blowing

I’ve got an 86 (I think) S-10 Blazer (2.8 V6) and the AC in it hardly blows at all. Even on high you can’t feel it unless you have your hand right next to the vent. Just curious what are the things I should be trying/checking to work this out. Living in Texas I like my AC lol. One thing I’ve seen is to check wether or not the fan modes do anything, and mine has low - high modes working, so I don’t believe that switch is the issue.

Welcome to the forum. An incorrect amount of refrigerant in the A/C can cause the moisture to freeze and block the air from going through the evaporator. The fan will work fine on vent and heat but not on A/C. No water runs out the A/C drain because the cold radiator is frozen over like a bachelor's freezer.

Is it the airflow that is not sufficient? Do you get good air flow when on heat? Check to see if the evaporator is blocked with debris. Mine was packed with tamarack needles and itsy-bitsy ash leaves.
