Should I cut down the cordon or leave it as is? is there any ways to save it besides letting it grows up from root and start a new cordon?
I would say leave it be. Let a new one grow from the root, bring it up over the top of the cordon. If the cordon comes back to life, fine, if not, cut it out next year. What variety is it? And how old was the cordon?
Mark, thanks for the suggestion. It’s a 7 years old wine grape. Interesting things is I have another one, same cultivar that just 20 feet away and leafed out fine. Although, that one’s cordon is lower, closer to the ground. This one is 5 feet taller. In cold winter this 5 feet in air made difference. I collected a lot of scions early this year, I’m thinking grafting ，T-bud ，whole bunch of buds to the spur position , artificially create spurs for the cordon. I have never done before and am not sure this works or not. Without the leaf growing I am not sure if bark is slipping yet.
Agree with Mark,
If your scions have a good number of buds, you can use a growth hormone to treat them as cuttings and grow a new replacement in the event the vine does not produce new growth.

Annie,
I did some light reading and grapevines do not have adventitious buds so if there isn’t a single bud on the cordon visible it’s shot. What’s likely the case if you confirm there isn’t a single bud to pop is that under the scaly outer bark there is browning that you’re not seeing. On a tree with smooth bark you can see this off coloration which at times is reddish that appears like freezer burn, and under this is live tissue that will perish this season, and likely before the middle of July arrives.
There’s an old horticultural saying that states if something doesn’t wake up by the middle of July, that it’s not going to. I once waited for a Dawn Redwood to wake up and it was almost the middle of July that it finally did and it began growing as if it never missed a beat.
I hope something good happens for you.
