check your coolant ASAP. If your coolant is low, you see any signs of oil in the coolant, or signs of coolant in the oil you may be losing it to a gasket leak. Have a mechanic check your intake manifold gasket. This is huge problem with the 3.1L engines and can lead to engine failure if not fixed early.
Signs of oil in coolant would be stuff floating in the reservoir and muddy colored coolant. Signs of coolant in the oil could be lots of white vapor (water) in exhaust and light tan foamy stuff on the oil fill cap or around the hole for the cap. For no heat, there are other things you could check like your thermostat and water pump but the failed gasket will kill the engine. I only mention this because the heater in my Lumina took 10-15 minutes when it did work and not getting my gasket fixed killed the engine.
