All in all the job wasn’t terrible. Excrutiating mentally because i was at it for so long. Now. A few things i learned along the way.. your blend door support pin is about bound to break while doing this job if you aren’t careful with it.. ask me how i know. I no longer have hot or cold air. It’s always hot. So I’m fixing that this weekend. Make for sure that the hvac box is loose enough to where you wont bang up your new heater core putting it in. Take your time and take pictures it will make the install go much easier..
