The thermostat probably is opening up too soon, not allowing engine to get up to temp. This is more than likely the case if both fans stay on after you turn the engine off.
I have the same problem with my 2001 Impala. After some number of miles or months, the temperature gauge will stay at its lowest point, no heat will come from the vents, the engine performs slightly lower and when the engine is shut off the fan runs for some time afterwards. The only way I can fix it is to disconnect the battery for a few seconds and reconnect it. Then I am good for a couple of months.
