Turn Signals, and Hazards dont work? i replaced the fuses but nothin....what can cause this

 

mine had a problem like this but my right front park light still worked. check the light itself the sockets could have corrosion or the plug on the wire harness behind the lights for corrosion

some of my lights it was the sockets and others the wire had broken at the plugs for the harness
i guess from water/salt and mud

 

You should check the signals/hazzard relay, this is located on the drivers side under the dash at the left behind the fuses, one my truck (1992) in green. I have on ebay the OEM mazda workshop manual on cd for 1992 b-2200 b-2600i trucks, this is the cactory manual that cover all the parts of the truck, clikc here "Mazda OEM Manual"
