2005 GEM EL Works Sometimes

Ive been searching but have not found an answer. It has worked fine for a while with no issues however I cant seem to find what’s wrong with it perhaps the DC controller?

Turn key on the dash flashes on and off and there is a clicking noise like a relay on and off like when it normally works on the fuseblock.

Plugging in charger does the same thing dash lights flash on and off.

Randomly if I let it sit for a while dash will light up, power on and drive.

When it is powered on the lights, horn, and blinkers do not work. However, the wipers, ebrake buzz will work.

All batteries at least 13.4v 74v going into controller. All fuses are good…is there a solenoid or something behind the fuseblock?
