Recently on my 2004 U-320 my water pump stop working. I checked the electrical power going to the pump and there was none. What I have read makes me believe It could be a relay in the electrical bay. There is a bank of 5 behind the panel of the 12-volt section. How do I know which relay goes to the water pump? There's not a label on the main panel identifing the water pump, but there is a water fill label identified. Also are all the relays the same?
Any help would be greatly appreciated-Rich Carr
If it is like my 05 U320, you have touch panels that your water fill is in with the lights , then your fuse for pump is in the drawer under the refrigerator. ( that is if you have a RV style refridge) If you have a residential fridge I do not know where they put the fuses and control modules .
Check the water pump latching relay. Mine is located in the bay driver side behind the white panel. Don't know if it's the same on your 320.

Yes, check latching relay. Ours went out but easy replacement.
