Summary of the thread
A 2004 Hyundai Terracan diesel with weak heating was suspected to have a faulty water valve. After checking the obvious issues without success, it was suggested that the problem might be due to a faulty cable connection. Upon taking the vehicle to a workshop, a defective cable was confirmed and replaced, resolving the heating issue.

Yeah, I had a quick look at the connections but didn't see anything obvious. Was it visibly corroded, or was it more subtle?

To be honest, I couldn't see anything wrong either. I wiggled the cables and the plug a little, still nothing. I was about to lose it when I just decided to go to the workshop. They ran some tests and discovered that a cable was defective. I can confirm this diagnosis 100%. So, yeah, based on my own frustrating experience, I would recommend taking it to a shop.

Thanks for the tip! I took it in, and you were spot on – faulty cable. They replaced it, and now I have warm air again. Cost me 95€ Appreciate the help!

Oh, that sounds familiar. I had a similar issue with my Terracan. The heating was barely working, and it turned out to be a faulty connection. Did you already check the cable and plug connections for the valve? That was the problem for me. It gave me absolute fits!
