Are both heater hoses go in the heater core getting really hot?

i dont know, in the front vent nothing coming out no heat or its not defrosting? only in the front, the back defroster working,how do i check the hose?

There will be two smaller heater hoses going into the firewall those are your heater core hoses see if both of those are hot

if they are hot what that means?

then that means hot coola then that means hot coolant is going into your heater core. If 1 is hot and the other 1 is cool or warm that means the heater core is clogged. blen blend door.

how much would that cost to fix? and also do i have to buy a part for that?

Let's start with r the hose is getting really hot first.
