Basically this part is located under your dash a little more towards the passenger side of the truck. You should have the A/C discharged before starting work on this truck. You need to remove most of the dash, starting with the plastic parts on the front/bottom. Most plastic parts will be held on with clips at the top and bolts at the bottom of the panels. The metal components will be held on with bolts. All bolts should be metric and I recommend pulling out the front seats to give yourself some extra room to work with. I also recommend that you pull things off and keep them in order with their screws and bolts (possibly lay a tarp out and mark anything that you think may be helpful to remember when putting it back together and/or take pictures). This is a lengthy process and the evaporator core is all the way in next to the firewall in its own housing with the blower motor that you will need to take out.
Before taking the housing out, you will need to unbolt the evaporator core from the a/c lines under the hood which should be center/passenger side of the truck right next to the firewall (make sure you replace the o-rings, new ones will come with the new evaporator core which I assume you are replacing). There is no easy way to replace it, just make sure you disconnect the negative battery terminal before starting work on it and start making your way towards the core one part at a time marking any wiring as you go (masking tape and a marker works wonders). You may not have to remove the whole dash and the steering wheel, but it will make your life easier. If at any time you get stuck, please post a picture of the problem and I can advise. (If the picture won't post, try making it smaller first, which can be done in Paint). Let me know how this turns out.

    yes the evaporator core will be right next to the heater core and they will both be by the blower motor and all will be under the dash. Where is the problem in my solution? Do you need clarification somewhere?

I have 1999 chevy truck 2wd 1500 need to replace the heater core need help


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.

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.

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.
