We need to know the model of your shower. The Moen Positemp models have a balancing spool which shifts back and forth inside the valve to maintain the set temperature even if there are fluctuations of the pressure on the incoming lines. This spool can become stuck from hard water, debris, etc.

However, Moen makes at least 2 other types of shower valves, so best thing to do is turn of the water, take the valve apart and take parts to a plumbing supply house. You can also finds pictures and diagrams on the Moen website which may help you.
