I think 0.8 Amps is max for the aux water pump. Disconnect it or replace it.
The mono valve is probably fine. I would replace anything that isn't bad, without condemming diagnostics. That gets expensive. You might need freon, but your symptom deals with the Automatic Climate control system.

Have you tested the KLIMA relay yet???

My system is working well and my CD has not come in yet. Hence, I'll leave it to the experts.

I was going to add a 1.0 amp fuse to my aux water pump just as a fail-safe method not to damage the climate control panel. Does anybody else do this or am I wasting my time???
