Check thermostat.

You should check out the basic stuff out before replacing your thermostat. Probably which you need to replace.

Check to see if your Radiator Fan is kicking in.

Check to see if you have enough Coolant in your Radiator.

Check to see if your radiator has any air in it. Just run the car with the cap open, if you have any air it will burp it out.

wouldn't all of those problems make the car run hot? The OP's car is running cold.

lol run hot ftl.

its simple fix! cover half the front of the radiator with a pice of cardboard.
when your driving, the cold air cause the anti-freeze to cool down too much causing no heat from the air vents.

you need to make sure all of your coolant lines are clean and corrosion free around the necks were they clamp, that can cause little seperation between the seating surface and mist out coolant day by day driving. and make sure coolant is full and blead of all air when at running temp.

Could have a bad radiator cap, sounds like the system isnt holding pressure. Make sure the thremostat is operating correctly and an oem is best.
