We've got a 94 LS400 which the heater stopped blowing any hot air. First thought, thermostat. I've changed it twice---no change. Next, heater valve, or heater core. NOPE clean as a whistle through and through. Tried the valve manually in case it was broke, nothing again. Flushed and filled. Changed all the hoses. Nothing. Relays, fuses, OK, OK, OK. NO CODES SHOWING. Vent motor is working. I have had almost everything out and checked. ZIPPO. I'll take any ideas before I'm completely gray headed. Thanks!
