There is a black covering on passenger side that should have four screws in it. You should find the heater core hidden inside the casing.

I would like to know how replace my heater core on a 2001 S10 chevy blazer


Instructions
    • 1Remove the dashboard. The heater core in S10s is behind the main dashboard, and it must be removed to access the core. The front dash panel can be removed by unbolting several screws at the bottom of the panel, then pulling the panel away from the dash. Once this front panel is off, the primary dash can be unbolted from the firewall with four large bolts below the windshield. Several accessories may need to be taken out to unbolt the dash from the firewall, such as the radio or 4WD switches.
    • 2 Drain the coolant from the core. There is a drain plug at the bottom right of the primary radiator that will empty the coolant system when unscrewed. Some residual coolant might remain in the core, but it will come out when the core is taken out
    • 3 Uncouple the core from the coolant lines. These hoses are directly behind the oil filler tube and will come loose when squeezed with pliers. They are of different sizes, and it won't be necessary to mark them for later re-attachment.
    • 4 Unbolt the core from its mounts behind the removed dash panel. Several bolts might be difficult to reach, but once free from the mounts, the core assembly slides up and out toward the interior of the truck. Lay a towel down when removing the core, as come coolant might splash out.
    • 5 Insert the new heater core and bolt it into the mounts. The openings will fit into the holes provided in the firewall.
    • 6 Reconnect the heater core hoses, and re-attach the dashboard and front panel.
    • 7 Fill the coolant system with a 50/50 mix of antifreeze and water. Tighten the drain plug on the radiator, then fill it. Crank the truck up with the heater system on its maximum setting and continue to pour coolant into the radiator until it will not take in any more.

Passenger side bottom of heater box remove bolt. Engine side on fire wall behind distributor remove nut. Now, on top of evaporator box remove small plate with wires on it. Look inside, remove that bolt. The heater box will come out. There are only 2 bolts and 1 nut to hold box in place.

Remove the heater hose clamps and the hoses from the engine side of the firewall. From the inside under the dash on the pass. side, remove the lower panel screws and slowly pry the lower cover down and the heater core will slide out of the heater box. Installation is reverse of removal.
