On both sides temperature is the same? If only on one side, I would then remove plastic above foot area and check if arm is moving up and down. For upper position being for cold air, and lower position for hot air.
If temperature is same on both sides, check for air in the system.

Yes i would also Imagine it is air there should be valves on the small houses going through the firewall, it can be difficult to bleed this system.
