R129 left side indicator lit

[BAZ-500SL]

Hello , need a little help, I'm staring to work on my r129 after a long time and it normally is ok but Today I connected the battery and the left side indicators were lit and also the turn signal ok the dash was lit, when I engaged the left side signal nothing happened just stayed lit, also when I did the hazards it stayed lot but then it began to flash , I did find some condensation inside it so don't know if this might if triggered something off or if there is something else I can do to check why it's happening, keep your suggestions coming need to sort it out thanks

Sounds like a sort in the light board. same thing can happen if you push a bulb in too far.

I know this sounds obvious, but is the battery fully charged ?
