New house, monen facuet in lower bathroom has cold water going through it but no water coming out when you turn the lever over to the hot side. Sink beside shower has good hot and cold water. No other issues throughout 3 bath home.

Shut vthe water off to then valve, open the faucet up and remove the cartridge. Check and clear the inlet ports on the cartridge. Before you button up turn on the hot water to flush out the supply and open valve. Good luck, Tom

What is the model number of your faucet?
