Question about 1999 Saturn SL
Sounds like you have a clogged heater core. Sometimes heater cores can be flushed, but more times than not, it has to be replaced. If you've replaced the thermostat and your lower radiator hose is always cold, chances are it is the heater core. Hope this helps! Have a great day!
