    Trying to find out why my passenger side is always blowing hot... Both valves are moving freely, so I think it must be wiring.

    I've pulled the plug out, and on one of the wires i'm getting 12v at cold, and 0v at hot, thats how it should be, but the other wire is giving me nothing hot or cold.

    Any suggestions please ?

    Thanks,
    Ferret !

    Your heater panel is bust i guess?

    It looks like 12v closes the solenoid and cools the car, so maybe that means you don't have to fiddle with heater controls when bleeding, as with the power off, the solenoid might be open...

    That'd be an interesting turn up for the books.

    Yes, valves are open with no power. You have to apply 12v to get them to shut !

    Billy - Dual zone climate.

    So in that case then, you don't need the heaters on hot when bleeding...
    Everyday is a school day.

    If your filling the coolant with the ignition off, then you don't need to set them on hot.

    Once i've put the valves back on the car, and I top the coolant up, i'm not gonna bother with the ignition

    My multimeter is shot - There's nothing wrong with the control unit, or wiring, so it must be the valve solenoid thats burnt out.

    Looks like i'll have to find another one from somewhere.

    TheEnd - I've just had a look at the heater valve on my Saloon i'm braking (It's a single valve, non-climate), and unless the spring inside the solenoid is damaged, then the valve on that is closed with no power. There doesn't feel like there's a spring on this one. I can tip it upside down and the valve will open.

    But on my Coupe with the Dual Zone Climate, there are springs on both valves, which are open with no power.

    So abit more research might be needed before being able to say that you don't need the ignition on when filling the coolant.
