I have one bathroom that does not have cold water but hot water only the kitcken is fine and the other bathroom is fine

Does the toilet work? Is there only one fixture that is not getting cold water in that bathroom? Please give us details.

Is there just a sink or is there a tub or shwer too? How are they working? This could just be debris in the cold inlet of the valve. Is the sink one handle or two?

The shower is one knob you turn right and left .left for hot and right for cold I have hot water coming out of my shower the sink in the bathroom comes on and I only get hot water no cold water coming out the kicken and the rest of the house is fine. Their is a tolet in the bathroom it's not filling up with water but my other tolet works
