The dash gauges are notoriously inaccurate. But it is possible that the thermostat is stuck open. Does the upper radiator hose get hot after engine warmed up? Also feel both heater hoses-when engine is warm, both should be hot-indicating the coolant is circulating through the heater core. If heater hoses are hot, and you still have cold air, the temperature blend door on the heater case may not be operating.
Try a new thermostat and see if engine warms up faster and better.

could be anything from belt noise to lifter tick to rod knock..lifter tick is under the valve covers..rod knock sounds like hitting the block with a hammer..if its rod knock see what your oil pressure is.. should be around 30 to 45 psi cold..warm will be as low as 15..depending on oil type..most lifters can be adjusted by removing the cover and doing adjusting depending on the vehicle..good luck
