Hello, my heater core has gone out and I need to take the dash to access it. Has anyone done this before on the same model and know the steps that need to be taken? I have taken a photo of how far I have gotten before becoming stuck.

I am attaching the info from the manual on the heater core. Unfortunately it is not very detailed so I did an internet search and found some videos on some similar vehicles which could help so I would recommend looking at similar vehicles like a 1990 Grand Am.

Here is a guide that will help in more general terms:

Hey there! Just want to say thank you again for the diagram and what car to YouTube. That solved it for me (just needed to look for more screws), and I was able to get to the heater core no problem. You literally saved me months for a new car payment as I was ready to give up! You're the best!
