gregg's flushmount and libertek relay

Hi guys,

I have a problem with gregg's flushmount. My left flushmount doesn't do anything. The right one is flashing.
I have installed the libertek relay and I think its working well. I can adjust the flashing rate with the screw.

I have switched the flushmount and still the left one doesn't work. (so the gregg's are oke)

The red light is flashing on the relay (Is that normal if installation is done))

Is there a problem with a fuse?

I hope some one can help.

Thanks
