Hello, my name is ***** ***** I'm here to help get your problem solved.

The best way to unclog heater core is by flushing it out with a garden hose. You will want to disconnect both of the hoses going into the firewall then use a garden hose to flush it out from both directions. I'd expect this to take you around a hour or two and a shop would charge about a hour labor to do this. Let me know if you have more questions or if there is anything else I can do to help. Thanks.

Would there be any problem with water getting inside of the vehicle that way and is the heater core below the glove box roughly and the to hoses should connect from inside the firewall do I need a hose adapter of some sort or just do the best I can with the garden hose do you know what size the hoses are roughly and there is only one spot to do this correct
There is not several of these areas in the firewall just trace from radiator to this heater corePlease

No water would not get inside by doing flush. If coolant was leaking inside right now then that would mean heater core is leaking. The hoses go into firewall right behind engine, pretty much in the center. You can make a adapter with a slightly larger radiator hose or just duct tape garden hose to heater core hose. Let me know if you have more questions, thanks.
