Many states building codes require a pressure regulator and expansion tank for hot water heater installation. Check the pressure regulator if you have one as this would only affect the hot water pressure. Adjust or replace. Rap the expansion tank like knocking hard on a door. Hollow sound is good. Dull thud means it needs to be replaced as it is filled with water.

Do you get hot water at other faucets? If not, check to see if the valves at your hot water heater are completely open. You may also have a blockage somewhere in the hot water line.

If you aren't getting hot water at just one faucet, it's likely that the hot water side of the valve needs to be repaired. It could be that there is a blockage in the valve that needs to be cleaned out, or seals in the valve may need to be replaced. Rebuild kits are available for many shower faucets at your local hardware store.

Be sure to turn off the water supply before attempting to disassemble the shower valve.

I think you are on the right track. The first thing I would do is change the cartridge. While you have the valve apart examine the inlet ports as good as you can to see if there is any mineral buildup. You can use a short length of a small gauge mallable wire to run into water ports to se if you can break anything loose. Another thing you can do is to turn supply stop on slightly while you have the valve disassembled to wash any particles out. Hope this helps you and thanks.
