Trying to replace my heater core (ugh). My question is, does the duct/tube that screws to the front of the case pull out from behind the center console, or is there a screw on the left side somewhere, i have pulled on it, bu im afraid Im going to break something.

Just finished replacing the heater core on my 85. I needed to watch four different YouTube videos to get to the heater core. What the don't show you is how difficult it is to get the screws back in. I spent 8 hour taking it out and probably 16 getting it back in. Invest in swivel sockets and flexible extensions. Make sure to find a good photo of the heater box to make sure you have all the screws identified. I have two the were hidden. You hands will be cut up from all teh sharps edges. I would need to think long and hard about doing this job again.

I don't know if this is the same on later C4's. But if there is a plastic clip thing inside the box for the heater door rod, make sure to find the part number and order one and replace it. As those things can break and so might as well replace it while it's apart.
