2013 GL550 NO HEAT (help)

Hey everyone,

I’m getting cold air when the heat is on in the whole car. There are times where if I drive for long periods it might warm up slightly but for the most part it’s all cold.

What are possible causes?
I don’t have a trustworthy mechanic unfortunately (still in the process of finding one) so I would like to be aware of possible reasons why it’s pushing out cold air.

Also, passenger side tends to be much colder than drivers side and on drivers side, the left vent closer to the window sometimes is warmer than the other drivers side vent.

Thanks in advance everyone!

Hey is there a heater fuse I can check? I can’t find it on the diagram.
