Edit:I was just looking at mine a realized that the heater core isn't in the evap box.So I guess you have to get to it from under the dash.I don't know what I was looking at when we did my evap.
Yup you have to pull it from the inside and its a PITA...These are the steps in a nut shell...
Step 1. disconnect Battery Pos & Neg
Step 2. disconnect heater hoses, if not already done (leaking=by-pass till fixed).
Step 3. Pull PCM
Step 4. Pull glove box, center console bezel & radio, insturment bezel & cluster, Fuse block cover, Both kick panels, hood release, parking brake release handles, lower dash cover & metal plate, passengers side air bag.
Step 5. Remove Steering column support nuts (4 of them) and lower column on seat.
Step 6. move engine main fuse block aside and back off main wiring block bolts at firewall & disconnect harness. Pull block plastic retainer. Then from under dash pull harness from firewall on inside.
Step 7. Pull defroster vent bezel from top of dash...be careful and use a wide blade scraper or thin wood wedge.
Step 8. remove HVAC lower nut on passengers side.
Step 9. disconnect 2 vacuum lines from firewall and multi line vacuum gang plug.
Step 10. remove dash support bolts (1 right side, one top right, 2 top left, 2 left side). Note leave right and one left side bolts slightly in place to allow dash to slide forward on and help support it until your ready to pull the HVAC box.
Step 11. pull wiring harness tabs on backside of dash (glove box side) as needed to allow dash to move forward.
Step 12. Remove PCM heat shield and ground.
Step 13. Remove 3 nuts on HVAC box in engine compartment, one on firewall behine engine and pull HVAC box forward. Now remove hidden nut top center of HVAC and 2 more nuts on studs behind box.
Step 14. Pull HVAC box from inside loose.
Step 15. Get a friend and remove last 2 bolts supporting dash and pull it back. Have friend help support pasengers side of dash.
Step 16. Pull HVAC box down and out.
Step 17. Remove 6 small screws from top of box and pull core out.
PS: I added a extra small hose clamp on one of the metal lines from the core where it comes thru firewall and ran a wire from the clamp to ground.
