When I turn it on all that comes out is hot water. The cold is not coming out at all. It's a single handle shower and tub. It's a Peerless brand. The supply lines are behind the tub enclosure and I can't get to them without tearing out the wall. I turned the water off, took the insides of the handle out, removed the two springs and washers. When the water is turned back on without the stem, water comes out the hot side but nothing comes out on the cold side. Any suggestions?

Inspect the room or area behind that tub valve, maybe a closet or spare room. You may need to cut yourself an inspection door. Before doing that can you follow that cold pipe any further through the house or is it totally enclosed in walls. There is an obvious blockage somewhere.

Thank you so much for your help. I took the part to Lowe's today before I received your answer. I believe the part is a deverter? (brass plug). It was locked up. The sales person at Lowe's broke it up and cleaned it with a wire brush. I brought it home, put it in and now everything is working as it should. Hopefully this can help someone else if they have this same problem.
