look under the sink where the pipes are. the sprayer should be coming out of the bottom of the fixture near the center. imagine the fixture to be like a cross. water comes in the two side arms, one line goes up ( faucet) and the other goes down (sprayer) the two water lines meet a ball via two spring loaded rubber seats. when you go to hot there's a hole in the ball that diverts water to the upper arm and lower arm for flow to go. same with the cold. for a mix part of the cold is exposed and part of the hot is exposed. shut off the supply and take apart the faucet till you see the spring loaded seats. turn on the water hot then cold a little bit to flush anything inside the valve, make sure the seats don't pop out. putting them back is no biggie. then take the ball and run a pipe cleaner through the holes. then put everything back the way you removed it. take special care to see the small pin coming out the ball lines up with the recess in the valve body. snug everything up and try the faucet.
