sounds like a broken or lose wire.

check relay and hazard light switch as the switch is not often used they some times gum up operate the hazard switch several times

is a new hazard switch you replaced it with and check to make sure the hazard swith is coming all the way out if it hangs just a little bit it will be in a neutral position and the turn signals wont work and if thats not it your multi-fuction switch feeds the turn signal lights it could be faulty

Look on the back of the fuse board ,for this you have to drop the fuse board as their are two fuses at the back and i know one is for the central locking ,the other ? Now when the hazard switch is disconnected the indicators shouldnt work but the only thing i can think of is the indicator unit is faulty ,do the hazards light the indicator lights up and they dont flash or is nothing happening?

Sometimes when the spark plug cables are dying (or are from a lousy manufacturer) it affects the dashboard. Happened to me when i had a 97 Polo, check that, it could be the same problem.
