Sure, thanks. Climate panel would be another point to start today. Found this

So radio and cage out. Do I just then have to open those two screws to take climate panel out. I do not undersrand where it "dissapears" in this case. I ask just to avoid romving parts which are not necessary to take out when removing climate panel.

Thanks DG for your patience. I might have followed wrong harness, new trial today. Actually all wires go inside neat plastic tubes connected to each other with isolation tape, no physical damages seen anywhere. Let's see what I find.

Many wires...; some help still needed.
So X3 and X30 round connectors, are they those in my pic. below?
, most left one is empty? Anyhow, I did my best but I think that the wire from that pump below expansion tank goes to relay box. Can I be that wrong? Eleven relays. I checked that earth is OK in the pump connector and allways when iginition on I get 0.4V to plus.

OK, thanks, have to study starting from the pump side, alredy saw yesterday evening that the cable from pump goes first to front and then turn left, goes under radiator and then turns left (back) in front left corner. Then it climbs up towards main relay box. If i understood right X30 is the first one from this direction; from pump to climate panel.

Strange, my colors do not match but they are from real life.
Homework part 2:
Engine hot, cabine cold, set point HI, auto pressed, ignition off
0.4V in second pump
and when air condition off but ignition on
0.4V
and when air condition off and ignition off
0V

So if no relay bad contact somewhere, if relay the perhaps broken relay.

1. At least Finnish version do not give a temp, If someone have other language versions available would be interesting to check.
2. Pump tested yesterday with 12V supply, it spins and I can hear that the water start to circulate. Might be the relay, I get 0.4V there to the wires. Which relay it is? I saw No. 22 here for X25XE and X30XE Lower one! Perhaps the lower one is for Y26SE and Y32SE Which I have (Y26SE)?? Relay 22 is named 'Pump Coolant' but is it for first pump or for second pump or is this relay for northern countries' second pump somewhere else?

Thanks DG for your quick (as usual) reply.

1. Yes cab sensor is ok; when driving and having set point in both sides e.g. 20°C fan speed is low and silent. When changed to 22°C fan accelerates and start to push hot, when changed to 18°C (from 20°C) fan accelerates and start to push cold.
2. I was in my garage and engine was only warm not hot, motor was hot earlier so the outside temp sensor might still have seen hot temperature. But I remember I put temp set point to HI. Anyhow, I repeat this all outside tonight with hot engine and report back.

Omega Electrical and Audio Help / 12V Pumps in Cooling System

« on: 28 September 2022, 17:21:43 »

Hello all

As I live here in the north my Omega is equipped with two electrical pumps in cooling system. First one is behind the radiator and I beleive that every Omega has that. The second pump is installed to the hose going to heater matrix. As far as I know the idea of this second pump is to increase hot water flow throught the heater matrix in these cold countries. On the other hand according to the owners manual that second pump should circulate hot water in heater matrix when ignition is off and 'Auto' button is pressed. This pump together with the fan should keep the cabin warm as long as engine have some heat left.

This second pump works well as I tested it with 12V source. When I press Auto in cabin the fan starts to rotate but only 0.4V comes to the wires connected to the pump (measured when not connected). Where is that current coming from, is there a relay somewhere? Everything else works fine in the car so guess all fuses are ok.
