As i recall you don't have to remove the dash just a cover behind the glove box 4 to 6 screws and the hoses
its a little hard to wiggle out without braking but can be done in a hour or so

You have to start by taking the black covers off under the dash. And you should look under the hood to see where the heater hoses go into the fire wall. that is where the heater core is located under the dash!
When you start taking the black covers off under the dash, keep removing parts tword the core location. It will be located in an air duct sence air has to blow through it in order to blow out onto the vehicle.

I have coolant steam inside my car coming from my heater - 98 chevy blazer


Hello
Your going to need a heater core,this is located in the heater fan box under the dashboard.
Possibly may be found mounted to the firewall under the hood.

Let it cool down before attempting any repairs.Another possibility is a broken hose at the heater core.

pretty easy to do. go to passenger side of dash and remove glove box for working room. there is a lower panel below the dash that needs to be removed. disconnect the heater hoses under hood. once panel under dash is removed you will see the heater box remove the 6-8 bolts around the very base of it, it will able to be lowered down and you will see the heater core it has a couple of brackets that hold it in place remove these. put new one in its place and put back together.

Antifreeze/coolant leaking from under passenger side dash


If it's your heater core, unless you're a mechanic you probably should get professional help. The heater core is located on the firewall and many parts need to be replaced to get to it. Do you see water on the floor inside the vehicle, Many times a heater core will leak inside.

Where is the heater core located on 2000 Chevy Blazer?


Its located under the dash, just behind the glove compartment. From what I've read, you have to pretty much remove the entire dash to get to it.

1988 Chevy Blazer Heater Core Replacement


first determine if the heater core is located high or low by raising the hood checking against the firewall {by following the heater hoses to the fire wall} if it is high need to remove the dash. if it is low get on your back and start removing clips and screws no special tool needed.
