The cache is NOT at the posted coordinates.
N 32° 47.??? W 117° 03.???
This is a 2-part multi-cache. The final location is along Navajo Road and is less than a half mile walk. To determine the final location, go to the posted coordinates and look for a yellow object. This object has several numbers on it so look for the 3-digit number, who's individual numbers added together equal 13.
Add 2 to this 3-digit number to get the North coordinates and subtract 51 from the 3-digit number to get the West coordinates.
The sum of the last 3 digits of the North coordinates are 15 and for the West coordinates they are 25.
