Check coolant level if low pressure check for leak, if both heater hoses hot check to see if your actuator I nheater under sahs is working.

Sounds like you might have a leak from your heater core. If its that then you are leaking coolant. It would also explain the no heat problem. Check the passenger side floorboard, if it is wet then it is probably the heater core.
