Turn Signal Problem ?

[Dibdob62]

My turn signals were working fine till yesterday but now the Drivers side front ones are not working including the bulb in the dash cluster. The rears are working fine and all the ones on the passenger side.

I've got power going in and out of the block attached the steering colum for both sides but not at the block that plugs into the back of the cluster only got power for the passenger side turn signals not the drivers side.

If I hook up power to the loom running from the bulk head block to the turn signals they work fine so its not in the loom up front.
