Question about Buick LeSabre
Check the coolant level in your plastic overflow container. If it is low or empty, it may just be there isn't enough coolant passing through the heater core to give you heat. Depending on the model you have, the source of any leak will vary. On 3800 engines a likely scenario is the intake manifold gaskets. If you have one of these engines remove the plastic engine cover on top and look in the valley where the front injectors are located. If you see any coolant pooled or oil the intake manifold gaskets are at fault. Hope this helps.
