Hoses in and out the same temp? Not the thermostat. You have a buggered up heater core. No heat transfer going on. You back flush it and it may clear up. Probably not. If it does actually get cleaned out, it will leak. Bite the bullet and get a new core. My son just went through the same thing with a 93 corolla. Sorry.
