My front turn signals and dash indicators quit working. The rear signals work great and as they should. The hazard light switch is kind of messed up and doesn't work. The car is 73 240z. Could the hazard switch be the problem? It is the in dash type of switch. Thanks.

Yes. The wiring diagram in the BE section on the electronic version of the FSM at XenonS30 isn't terribly clear, but the turn signal wiring passes through the hazard light switch. Describe the behavior of the hazard switch and maybe someone can give you advice on how to repair it.
