Toyota Repair: Camry 87 model, problems with turnsignals, turnsignals, turn signals

Question
When I switch on the turnsignals to left or right, all four light blinks (like hazard).. if you know what I mean. Is this something you have stumbled upon in the past? Nice to se someone with the same last name as I have o) Not very common where I com from.. Thanks in advance..

Answer
First check all the bulbs for the turn signals and also in the rear at the tail/stop lights, make sure the bulbs match the sockets, some of them have one contact and some have two, the other problem may be the turn signal/ combination switch and last some sort of wiring problem.
