I'm currently changing the evaporator core on my Intrepid and I must say, I clearly see why places charge ALOT to do it. Since I'm taking damn near everything off I decided that I'm going to do my ATC conversion as well. I haven't gotten the evaporator core off yet but I am wondering, since I am so close to getting it out. I know there are three screws on the firewall behind the engine that need to come off in order to access the heater core and evaporator core. My question is, to anyone who has ever done this change, the instrument that holds the both cores, big black thing that sits behind the dash, after the screws are removed, is there suppose to STILL be a difficult time pulling it out? Everytime I tug on it, it feels like at the bottom there is still a screw or something holding it in place but when I checked I found nothing.
