Dropdown Menu Highlighting Issue

I’m still trying to figure out this issue with my drop down menu for this site. https://0364e38.netsolhost.com/wordpress1/

I would like the parent page along with the current page to highlight blue depending on what page is active. I’ve been able to create code so that the current and the parent from the main nav highlight blue, but have been unsuccessful in getting the second level subnav parent to highlight without highlighting my entire 3rd level list of pages.

Here’s my code.

#header ul.nav li ul li.current-menu-item a,
#header ul.menu li ul li.current-menu-item a,
#header ul.nav li ul li.current_page_item a,
#header ul.menu li ul li.current_page_item a {
color: #165B94;
}

#header ul.nav li.current-menu-ancestor a,
#header ul.menu li.current-menu-ancestor a,
#header ul.nav li.current-menu-parent a,
#header ul.menu li.current-menu-parent a,
#header ul.nav li.current_page_parent a,
#header ul.menu li.current_page_parent a,
#header ul.nav li.current_page_ancestor a,
#header ul.menu li.current_page_ancestor a {
color: #165B94;
}

#header ul.nav li ul li.current-menu-ancestor a,
#header ul.menu li ul li.current-menu-ancestor a,
#header ul.nav li ul li.current-menu-parent a,
#header ul.menu li ul li.current-menu-parent a,
#header ul.nav li ul li.current_page_parent a,
#header ul.menu li ul li.current_page_parent a,
#header ul.nav li ul li.current_page_ancestor a,
#header ul.menu li ul li.current_page_ancestor a {
color: #165B94;
}

#header ul.nav li ul li a:link,
#header ul.menu li ul li a:link {
color:#fff;
}

Can someone help?
