Drywall seam "pops"

We are fixing up an old summer cottage in southern Michigan. Last fall we installed and finishsd (and even painted one room) of drywall, but left the building unheated in the winter. This spring we see that the tape on some of the seams has slightly popped up creating a small "ridge" between the finished pieces. Is there a way to fix these without pulling off all the tape and starting over? For example, slitting the tape on the seams and putting new compound on, or caulking? Or do we need to pull the tape off and start over?
Thanks for your help.

yes you'd need to pull the tape off and start over. fiberglass mesh tape might work better but since you are not heating the cottage maybe you should reconsider your choice of finishing materials. the problem will probably happen again drywall plus closed up unheated at least minimally and dehumidified in the winter cottage plus drywall is not a good combination it would be like putting a wet sponge in your freezer.

I would also say that the tape needs to be pulled off and retaped. my suspicion is that the paper tape was put on backwards. when you look at the tape you will see a line down the middle of the tape and that is where you fold it for the inside angles. it should be applied to the flats on the wall with the ridge on the paper turned towards the wall. make sure that the mud isn't too stiff when taping and that it is put on generously and then wiped tight wiping out the excess from under the tape, let that dry before adding each additional coat. if you add the mud with out letting it dry it will have a tendancy to pull the tape loose or form gas bubbles under the tape.
