2003 Ford Explorer Sport Trac - AC issues

A/C runs hot and cold. First it puts out cold air. Then it seems to stop and just recirculates the warm air. The hot and cold cycles are several minutes long.

Probably freezing up due to low refrigerant. Take it to an AC shop that can put gauges on it and diagnose the problem. AC is not a DIY system.

Thanks for the advice. I hope that is all it is. I’ve done ring
jobs and valve jobs but don’t have any equipment for working on A/C.
