The glue on the original fabric headliner installed in the Chrysler Crossfire interior is prone to drying out in dry cold environments. Moisture in highly humid climates makes the headliner glue lose its adhesive nature, and the weight of the headliner makes the fabric sag as it separates from the headliner substrate.
Since I moved from Alaska, where it’s cold and dry to the midwest where it’s moist and humid, it spelled disaster for my headliner. First, I freeze-dried it up north and after about four years in the sweltering heat of the midwest, the headliner started falling in around me.

If your headliner is beyond the quick fix, that’s OK. Once it gets to this point, the headliner adhesive is already shot so you may need to graduate to the next step, recovering the headliner substrate and full replacement of the headliner fabric.
