Step 2: Unscrew The Nuts 

Now locate the plastic nuts and try to unscrew them by hand. If it is tight, use your basin wrench to do the job. If the nuts are hard to open, use a few drops of penetrating oil to loosen them up.

After applying the oil, wait for some moments, then try again to unscrew it. 

Still not working? Then take a drill machine to drill on the side of the nut. Then, use your screwdriver and put it in the hole. Rotate it until you can remove it. Solving this problem is as easy as replacing a faucet.
