I have a glacier bay single tap with built in sprayer that has no pressure in the hot when you turn the single stem towards hot it just dribbles, the cold has lots of pressure any ideas?and yes the waters turned on all the way

Disconnect the riser pipe on the HW side of the faucet. Now, put the riser in a bucket and turn the stop on. Have water? If no, you have a blockage in the stop or riser, maybe a loose washer. If so, you probably have some debris in the hot water port of the stem. Turn the water off at the stops, disassemble the handle and pull the stem out. Look for something in the small side hole on the hot side, perhaps a piece of washer. Turn on the HW stop and purge the line before assembly.
