Porch Light

[GDB]

Hi!

I have a 2011 Sprinter 318FLS.

I cannot get the Porch Light to come on.

When I turn the switch on there is a small red light that illuminates briefly, then a flashing blue light comes on for a couple of minutes followed by a flashing green light, which stays flashing but the light itself does not come on.

I suspect the light is motion activated as there appears to be sensors on each side of the light.

Your suggestions are greatly appreciated.

Thanks from Alberta Canada
