blinker problems

I have an 89' grand marquis. Im having problems with the turn signals. I have replaced all the taillight bulbs, flashers and there are no blown fuses and I still cant get the turn signals to work. The hazard lights work so Im pretty sure that there isn't a problem with the circuit so Im wondering if there is a hidden fuse link anywhere that might need replacing or if the whole signal switch on the steering column is bad. Before I have to chase wires I want to know what i can try before I start that process.

Did you fix the problem? I had the same problem on my car. It ended up being the 4 way hazard switch. Hold down the 4way hazard switch and see if the turn signals works. If you look on most wiring diagrams, the turn signals and the 4 way hazards tie together.

Make an enlarged copy of the wiring diagram, test each component in the circuit until you find the fault.
