As long as your climate control is working I would check two things.

1. Top your coolant off-to include the reservoir
2. Check the operation of the heater VSV just to the drivers side of the charcoal canister. You should see movement from this valve if you go from cold to hot on your temp ****.

Start there

 

Is the thermostat opening?
