AC fan has to be 'on' (not auto) for cooling

My AC for upstairs has been acting up.
-The blower comes on and sometimes blows warm air even when the thermostat inside temp is more than desired temperature. When I switch the off the cooling and toggle the fan setting to 'on' and again switch the system setting to cool. It blows cold air for few hours.
In addition the outside condenser unit shows water spilling out of drain pan.

Any insight will be appreciated.

Thanks

May be Thermostat problem. check lose wires in the thermostat first, pay attention to the yellow terminal/wire.
