i belive there is what looks like t perferated line in the plastic where the heater core is that you are suposed to cut to gain access to the heater core. i have never done this but i know several people who have you just need to make sure you get the access door resealed if you go that route or it may affect your heat. remember if you remove the dash instead of the other method you will have to have the a/c system emptied since it also circulates through that box.

Replacing heater core in 2000 GMC sonoma. Dash is


Usually the whole hvac box has to come out of the vehicle to replace the heater core. Once the box is out it can be opened and the heater core removed. Be careful with all the vent doors and actuators, make note of how everything came apart. The last thing you want to do is have to remove the dash and box because something wasn't on just right. Good luck.

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
