    Hi.
    I'm having an issue with my solar powered ventilation system.
    There are days when this system should kick in, but when I enter the car it's pretty hot.
    I've found that when this happends the ventilation system is set to recirculate. I've verified a couple of times that it's NOT at recirc when I leave the car, but when I get back into the car the system has set it to recirc.

    Have any of you expirienced this?
    I'm I doing something wrong?

    Best regards
    Espen Rønning

    Here are some tips in the manual that might explain why this may happen to you on some days. Worth testing out:

    The Solar Ventilation System may not operate under the following circumstances due to a lack of power from the solar panel:
    Low amount of sunlight
    Part of the solar panel is cast in shadow
    Part of the solar panel is covered by fallen leaves or dirt
    Solar panel is not at a high temperature

    Make sure that the “POWER” switch is in ON mode before turning the solar ventilation switch on. If the solar ventilation switch is turned on while the “POWER” switch is OFF, the air mode and the status of the air vents will remain unchanged.

    Tanks for your tips. I aware of those, and I have a hunch telling me this has something to do with lack of power.
    I live in Norway and the weather can vary a lot in a day so when the sun dissapears there might not be enough power to drive the system, but then again the system should restart when the sun returns?
    And why does the car switch the ventilation to recirc? At least this proves that the system is turned on.
