Ni3 yao4 你要 means "you want", and can be followed by a verb or a noun:
你要咖啡嗎？Do you want some coffee?
你要看一下嗎？Do you want to have a look?
It is used to express a volition or a wish.
Ni3 yuan4 yi4 你願意 means "you are willing to", and can only be followed by a verb:
你願意看一下嗎？Are you willing to have a look?
But 你願意咖啡嗎？ does not make sense
You can also see the nuance in the example above between 你要看一下嗎？ and 你願意看一下嗎？
