Depending upon your skill level and ability to twist yourself into pretzel like positions, Heater cores are the least fun things to replace. Check both sides for retaining screws (under dash & firewall side) Make sure all wires and control cables& devices are disconnected. Make sure that any attaching "tunnels" for defrost & A/C have been retracted.
In some extreme cases, I have actually intentionally(carefully) broken off a few fasteners which are virtually unreachable.Be careful not to damage A/C evaporator.If you are really stuck, get a good manual. Generally, when gently pulling on the heater box, you can get a good idea where it's still fastened or stuck!

I have a 2000 s 10 blazer heater doesnt work..but all fues are good and tried replacing swith in cab..no effect..but blower works just fine? Any ideas


Sound like a heater core, the heater core would be under your dash..Another sign of the heater core being gone, is you would notice the floor board being wet..It is possible that maybe at some point the floor board was wet and you didn't know here it came from and didn't give it another thought..But if the blower works..I would bet heater core...Or it could be a thermostate..check the thermostate first it would be the easiest.. and the cheapest..

Replace heater core


Instructions
    • Drain the cooling system. Draining the cooling system will prevent toxic engine coolant from leaking into the passenger cabin of the vehicle during removal of the heater core. To drain the cooling system, simply disconnect the lower radiator hose from the radiator by loosening the hose clamp and pulling the hose off. Be sure to drain the fluid into a sealable container and dispose of the coolant at an appropriate disposal site.
    • 2Pull the dashboard six inches rearward. In order to do this, you must remove the following parts; the center dash bolt (located under the defroster vent cover), the bolts under the driver and passenger kick boards, the bolt connecting the dashboard to the radio mount, and the the bolt connecting the dashboard to the rear of the glove box. The locations of these bolts are immediately apparent upon looking under the dash. Once you have removed these bolts, you can pull the dashboard rearward and secure it.
    • 3Remove the heater core box. The heater core box is a black plastic box that surrounds the heater core. This part should be visible when looking down into the dashboard from the passenger side seat. Remove the two bolts on top holding it to the firewall and another on the bottom near the foot well. After removal of these bolts, the heater core and box are attached to the vehicle only by the coolant lines, which you can now disconnect by reaching into the box and pulling them off of the heater core (you may have to loosen the clamps first).
    • 4Install the new heater core. This is accomplished by applying steps 1 through 3 in reverse order; re-connect heater core coolant line, re-install heater core box (be sure to apply silicon sealant to the edges of the box, hermetically sealing it), replace the dashboard and install bolts, and re-fill the cooling system.

I need to replace the heater core in my 1986 Ford Bronco 2. Are there instructions on line on how to do this?


under the dash on the pass side there is a large black plastic box. take out the 6 screws and pull off the cover. there is a wire attached to the top that controls a flap, that just lifts off. under the hood loosen and remove the 2 host clamps right at the firewall area. Push the metal tubes in to the firewall. Then reach back in from under the dash and pull out the old core. put the new one in reverse order.

Bad heater core


look undre the passenger side dash and you will see a black box. Look closely and you will see screws in it around the edges. remove all the screws then remove the cover,there is the heater core, held in by 1 screw that is kinda hard to see. next look under the hood on the passenger side firewall right in front of the dash, you will see 2 hoses with clamps on them. loosen the clamps and remove the hoses. you may want to drain the radiator first but I never do

Heater core


NO, BUT THE COMPLETE HVAC MODULE NEEDS TO BE REMOVED. THIS IS BASICALLY THE LARGE BLACK AIR DISTRIBUTION BOX LOCATED UNDER THE RH SIDE OF DASH. THE RH BODY MOUNT BUSHINGS ARE ALSO GOING TO NEED REMOVAL & THE BODY SLIGHLTY RAISED TO GAIN ACCESS TO CORE UNDERHOOD.

Have the dash off but can't get to heater core on chevy s-10 blazer 1998


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.
