Should be on the passenger side kickplate below the glovebox and to the right. You may have to remove the plastic panel to access it or look for a small hole in it and feel around for the button

SOURCE: How to replace a heater core in a 1994 chevy 1500

As with all vehicles it seems the first part that they build around is the heater core. It is under the dash above the floor housed in a black plastic sealed box. Sealed with goop. Locate that box and start removing everything around it that is peventing taking the cover off. Of course disconnect the heater hoses under the hood a thefirewall.

Warning it is never as easy as it sounds.

SOURCE: I have a 1999 chevy silverado and I need to change heater core

Not a whole lot different. Just need to keep removing plastic down at the heater until you get to the heater core. Then disconnect it on the firewall side.

If i remember correctly you will have to remove the dashboard to get to the a/c box on these trucks. Then you need to disconnect the heater hoses and remove the a/c box. Then take the A/C box apart and replace the heater core.

I just got a 1999 chevy silverado 2wd and the temp reaches 210 but the air dosnt blow hot


1.)heater core restricted-check both heater hoses coming from the heater core if one is cold your heater core is restricted and you will need to flush the core.
2.)Your air mix door actuator in the vehicle is inoperative and you will need to replace it.It is located on the bottom of the heater case in the center of the vehicle.It mounts straight up with a couple bolts.

How do i change the heater core on my 1999 chevy silverado 1500?


Inspect/Replace If it is necessary to remove the heater assembly, the cooling system must be drained before removing the heater core.
When a heater core leaks, a new heater core is installed or the old one repaired.
Heater Housing
  • The heater housing is usually under the dash and must be removed to gain access to the heater core.
  • Procedures for replacing the heater core vary with the year, make, and model of car. It threfore necessary to consult the manufacturer's repair manuals for the proper procedure for replacement.
f74-01.gif The heater housing is disassembled to get to the heater core. Heater Core
  • Remove the access panels(s) or the split heater/air conditioning case to gain acess to the heater core.
  • Remove the heater coolant hoses.
  • Remove the cable and/or vacuum control lines (if equipped).
  • Remove the heater core securing brackets and/or clamps.
  • Lift the core from the case. Do not use force. Take care not to damage the fins of the heater core when removing.
  • To reinstall the heater core, reverse the removal steps.
When the heater core leaks and must be repaired or replaced, it is a very difficult and time-consuming job primarily because of the core's location deep within the firewall of the car. For this reason always leak test a replacement heater core before installation.

I have a 1995 chevy silverado 1500. the heater hose bursed. do I have to remove the dash board to repair it?


The heater hose connects to the heater core through the fire wall, under the hood, remove heater hose clamp at fire wall under the hood, remove clamp at other end, install new heater hose, no you don't have to do any thing under the dash.

How do I get to the heater core (through the dash_, but is it on passenger side? I am having trouble getting the bolts off. Truck is Silverado 1999 Z71 (1500).


I just replaced the heater core on my 1997 S-10. If your chevy is anything like mine, the entire dash has to come out. I recommend buying a Hayne's manual for it. Those books are life savers.
