A/C condensate drainage problem (I think)

[y3llo]

1992 explorer. My A/C works well for the first 10 minutes. Then it starts to blow muggy air. There seems to be plenty of freon. Is it possible the condensation drain hole is plugged and that the system starts to recirculate the moisturized air? Can someone tell me where to find the drain? Thank you.

A/C drain problems

looking under the hood on passenger side on back firewall the drain hose is under the blower motor housing,remove the 4-screws and remove the motor from the housing and look inside.You may find leaves and other stuff that got in from top vents, this may help or maybe not
