[TdotAlero]

So I noticed for a little while now, since the beginning of the winter my Alero has problems heating up. I let the car warm up for 15 minutes every morning, and as I drive (traffic or highway - same story) the temp. gauge stays at 1/4 or even sometimes below that. It never really goes above 1/4 mark. I thought it was the gauge or sensor, but the heating in the car doesn't work that well either. I recently replaced my blower motor and resistor and it was fine until winter. So is it a possible thermostat issue. I really don't feel like replacing the thermostat so I hope there is an easier way around..
