My attempts to reglue the fabric did not last more than a few months.

The best solution to this problem is to go to the junkyard, and get the non-fabric version of this part. There is a good You Tube showing how to remove these A-pillar trim pieces. You pull at the top to separate trim from the pillar, exposing the black tether (loop). Twist its black plastic anchor 90 degrees and pull it out. Then slide trim piece upward until freed. The tether is a safety feature -- in a crash, it will not go flying.

I found a very good You Tube showing how easy it is to remove the A-pillar trim pieces without breaking the collision safety restraint strap:

Removed, you can re-fasten the fabric. I chose to use iron-on interfacing instead of glue. Whatever you use, strip away the old (dark yellow) adhesive first, to get a good sticky.

When reinstalling the trim piece, make sure to underlap the trim piece under the black door gasket.

There is a 3M fabric glue, spray can, suitable for high heat. I got a can from a fabric store. It doesn't bleed. Similar to contact cement for application.

The A pillar cover can be pulled off, but I would wait until the outside temp is reasonably warm. Cover the part of the A pillar that you don't want to remove, peel back the cloth, and lightly spray both the cloth and the pillar. Reattach cloth. Wait about 20-30 minutes and re-install.

Keeping it running is better than buying new

I did this job. It's very easy. Will post link.
