MKII Parker issues

Hi everyone, another annoying issue with the MKII ghia...

every single one of the parkers are out, along with the dash illumination and brake lights.

The headlight and high beams work, the interior light works, the fuses are good, the switch is brand new.

Im stumped as to what the problem could be
any help would be greatly appreciated...

Thanks

found the problem [:o)] the entire fuse block is stuffed...making very little voltage across the fuses and actually falling apart from underneath the fuse holders....
