Thanks for your replies folks. I have removed the faucet and it appears that it is defective and blocking the cold water. The water line is not crimped or blocked.
Now comes the fun part ... trying to get a new on. I did check with a local plumbing supply store but they don't have anything close. I have tried two local Winnebago dealers ... nothing in stock so they would have to order. May take several weeks if they are even available, so I'm told.
This is the second time this faucet has been replaced. The first time before I even took delivery 3 years ago. Now it has broken again. Why they make such cheap parts is beyond me.
