2001 olds intregue heat not getting warm in car why?

This could be a lot of things but I would try the most immediate solutions first.Do you have the correct level of coolant in your radiator?It could also be your thermostat not functioning properly and stuck open.It could also be your temperature sensor.Lastly and most expensively it could also be a clogged drier located in most vehicle under the dash board.Try a radiator flush if all else fails.
