My Skoda Octavia 2002 ambiente, hazards don't flash when I lock and unlock

Hi all Octy owners

My third thread really sorry.Since I was getting no replies

My Octy 2002 ambiente  I had just replaced some fuses of the hazards and turn signals as they had gone.Now everything works fine the alarm gets armed when locked and interior lights come on when unlocked all that stuff works well and the door sensors are perfect all the turn signals work and hazards But now when I lock and unlock, the hazards don't flash.Had just taken it to the electrician but he couldn't find the problem he says it will sort on its own he checked all the fuses and all the fuses now are perfectly fine.Plz advice

Regards

Sanjay
