I have a 1997 Saturn. The temp. gauge runs at a 1/4. Don't get any heat.
Blower fan works. Any ideas, help is appreciated. Thanks

Thermostat?
 
I would try thermostat first. Gauge should run between 1/4 mark and 1/2
mark while driving down the road with air going thru the radiator.

If that doesn't do it, I would flush / backflush heater core, try
again.

A typical partially clogged heater core symptom is hot water going in,
luke warm coming out. If a heater core is operating properly, you can
NOT feel the difference between the inlet and outlet temperatures.

I don't believe that the '97 uses a heater control valve so that should
not be an issue. The only other problem could be the air temperature
mixing door in the vent system, in the dash. Does the temperature
slider control feel like it is working? resistance?
