Why is heater not blowing hot air on 99 chevy blazer
\015 Was working earlier in season and now will not blow hot air. replaced thermostat, no help. both heater hoses going to the heater core are hot. believe this to mean that water is circulating. guage on dash shows correct temp. any suggestions?\015
If the fan blower is working then it must be the heater valve inline with the heater hoses. Or the selector on the dash has broken and is not connected at the back. You have tried everything else. You were correct in what you wrote above and have tried so far
