I have been having problem with my turn signals working. I changed out my hazard switch and they started working right. But then the next day they quit working again. I pulled it back out and was thinking that I might of blowed a fuse but all my fuse is still good.

When the turn signals quit working pull up , down , front to back an back to front on the turn signal switch handle . Do they work when doing this ? Pontiac had bad switch . The power for the turn signals goes through the flasher / hazard module . Could be the switch or the module.
The HAZARD LPS fuse in the left hand instrument panel (LH IP) junction block supplies battery positive voltage to the flasher module, which is part of the hazard switch assembly. The TURN LPS fuse in the LH IP junction block supplies ignition positive voltage to the flasher module. The turn signal lamps may only be activated with the ignition switch in the ON position. When the turn signal switch is placed in either the left or right position, current flow is from the flasher module's output to the turn signal switch assembly. The flasher module then sends an on-off voltage signal to either the left or right turn signals and their instrument panel cluster (IPC) indicator. When the hazard switch is pressed, all the turn signal lamps will flash including both IPC turn signal indicators.
None work , left , right , front or back ? Check TURN LPS fuse C 10 Amp -in Left instrument fuse panel ! More then likely it's the switch on the steering column or the hazard switch , power for turn signals come from the hazard switch !
Fuse Block - Left I/P- On the left side of the I/P
First check turn signal fuse and relay if, they are good then try pressing on and off the hazard switch while turning the signal switch on.If signals start to work replace hazard switch.If hazard switch is good then replace turn signal switch.
had the same problem as you. I replaced the relay twice before it worked right. Just to test if it is the relay what I did was when the turn signal quit working I pushed the hazard button a few times then the turn signal started working again. Good Luck hope this helped
