I've got the dash disconnected and pulled back far enough to get at the box, but can't get the heater core box back far enough to get the lid up. Does the AC drier have to be disconnected? Chilton doesn't ever mention AC discharge. I've removed all the bracket bolts/nuts and got the hidden screw that goes from the inside through the firewall. I've had to scrape the insulation that seems to be glued to the top of the lid and when I lay on my back in the passenger floorboard and try to pull the entire assembly away from the firewall it seems like that insulation down below is really holding it up.
I am not having fun.
