Falcon 2 Pro 40W

Hello all,
I am a user of the Falcon2 Pro 40W - and am delighted. But there is one problem: After 3 Weeks of use, the frontlight does not work anymore and the exhaust fan is not running anymore. I checked the cables, checked the auto and on switch for both fan and light - but no running fan and no light anymore. I saw below the connector of the light-bar(and connection to the fan) two blue switches.
Do you have an idea how to find out where the problem is? Do you have an idea what these two blue switches do?
Many thanks
Michael

Usually it’s the connector of the light bar. Is it seated properly? If yes and it still does not work, do you have a multimeter to check continuity of the cable pins?

Hi, yes, it is seated properly - I plugged it in and out and still does not work - is there maybe a plan which pin is power, which are ground? Yes, I try to check the continuity.
Many thanks
Michael
