Your question is like me telling you My car wont start BUT all my other cars and trucks start perfectly

You should give us a hint on the type /name of the shower and how old it is and if it is a pressure/ temperature balance type

It is a Mohen, and I assume it is 7 years old, that is how old the house is. When I turn the handle over to the hot side only a little bit of water trickles out.

The older Moen faucets had problems with mixing hot into cold water lines.

I would suggest you contact Moen and get a new cartridge and a diagram how to set the temperature limit

Does it sound like that is maybe the problem,I just need to replace the fixture? Thanks for your responses, I appreciate it.

Try replacing the cartridge first its a lot easier
