I have no heat in my 2013 Jetta.

What is your question?

I found the inlet into the heater core was a little hotter than the outlet. Im talking I could barely touch the inlet as it was so hot, but he outlet was hot, but just not as hot. The blower works fine and the thermostat has to be working as I would not be getting hot water at the heater core inlet. What the heck else should I check? Thanks for any help you can give me.

What makes this problem better or worse?

All the time.
