My sink runs cold and hot water just fine but when I try to use my shower only cold water comes out. Any information on how to fix this problem would be greatly appercaited.

Would need the brand and model number of your shower faucet, Thanks.

John is right we can't tell from what you have said so far. More info and/or pics are needed. Could just be a clogged hot inlet on a cartridge but we're just guessing without that info.
