The tail lights and hazard flashers work. There is power to the fuse in the fuse panel. I have replaced the turn signal switch in the steering column. Older vehicles had 2 circuits. 1 for hazards, 1 for turn signals. I am not sure whether this has 2 circuits or not but I can only find 1 flasher relay and it is wotking with the hazard flashers. Is there a relay on the fuse box that is for the turn signals but does not look like the hazard relay. NAPA says the turn signal relay and the hazard relay are the same type but don't say whether there is one or 2 in the circuit..
I have a similar problem but my left signal works, when i turn the right on it just does an annoying buzz sound. if you can think of any explination for such shinanogins help would be greatly appreciated

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.
The hazard switch gets power from the horn fuse which is hot all the time, and from the turn signal fuse which is hot when the key switch is on. The turn signal switch gets power from the hazard switch and both use the same flasher. So if the turn signals work but the hazard switch does not power the lights, and both fuses have power, I would say the problem is inside the hazard switch.
Assuming this has the V6, the 15A PARK LPS fuse in the underhood fuse block feeds constant power to the auto park lamp relay. When the relay closes, 12V power passes through the 10A INST LPS fuse in the right instrument panel fuse block to the panel dimmer switch and then to the five instrument cluster lamps.
If by "rear lights" you mean everything in the rear lamp assemblies, power for the tail lights (running lights) starts at the 15A PARKLAMP fuse in the underhood junction block, passes through the automatic lamp control (ALC) relay and the right instrument panel junction block to the tail filament of the dual stop/tail lamp and the separate tail lamp on each side. The 12 V power for the stop lamps is protected by the 20A STOPLAMPS fuse in the left I/P junction block, passes through the stoplamp switch when brakes are applied, stop filament of the dual stop/tail lamps. That leaves the turn signals and the hazard lamps. Power for the turn signals originates at the 10A TURNLAMPS fuse in the left I/P junction block and is applied to the hazard switch. Switch output goes to the turn/headlamp/wiper switch for selection of left or right turn signals. That switch output goes to the turn lamp. Power for the hazard function begins at the 10A HAZRD LPS fuse in the left I/P junction box and goes to the hazard switch. Switch output is sent to the left I/P junction box to make the turn signals flash. That's it. Post a comment if you need more information.
Guessed it's a V6. Trying to sort this out. If setting the headlamp switch to PARK turns on the park filaments of the front park/turn signal lamp and the tail filaments of the rear tail/stop lamps and the separate tail lamps, the park light circuit is good. If 20A fuse 6 in the power distribution center is OK, the combination flasher in the multifunction switch is receiving power. Power is directed to the turn signal lamps by operation of the turn signal/hazard warning switch. If the turn signals are not flashing, the combination switch may have failed or the turn signal flasher part of the combination flasher may have failed. Finally, the hazard warning switch causes the turn signal elements of the front combination park/turn signal lamps and the rear turn lamps to flash.
check the fuse if good then turn on the hazard lights if they work then you probably need a turn signal flasher which is a separate flasher unit then the hazard one.it usually looks like the hazard one so with the hazards on and locate it then you will know what the signal flasher looks like and you will also know not to change the wrong flasher unit.the signal flasher is often located at or near the under dash fuse panel or somewhere in the dash you don`t say what type of car your talking about.
For 1989 Jeep Cherokee the Flasher is located: * Front seating area, driver side, under dash, above kick panel, mounted in bottom of convenience panel for Hazard flasher * Front seating area, driver side, under dash, above kick panel, mounted in top of convenience panel for Turn signal
you don`t say but do the lights work either on the front/back on both sides.if not then it may be a fuse that needs replacing or need a bulb replacement.if the lights work but don`t flash then it sounds like a signal flasher problem.the flasher is located in the fuse panel under the dash on the drivers side.if the hazard flashers work then turn them on to find the hazard flasher by the fuse panel then you will know what the signal flasher looks like and change the signal flasher.make sure you change the one for the signals and not the hazard one.if the hazards work then i would say the signal switch is good as the hazards work through the same switch.
the hazard lights use a different flasher(relay)then the signal lights.you don`t say if the signals work on one side or not,you should check the fuses for the signal lights in the fuse panel under the dash on the drivers side.if you put the hazards on and find the flasher then you will know what the signal flasher will look like,it is on the fuse panel and replace they should work.
you need to check to see which bulbs don`t work both front and back lights for the signal on the side it`s not working,you don`t say if any signals work or not if no signals work then you need to check the fuses under the dash on the driver`s side.now if it`s just one side then check the lights as mentioned above.if one isn`t then replace the bulb.if neither bulb is working then it sounds like the signal flasher is not working.turn on the hazard flashers and check the lights front and back.if all bulbs work then leave the hazards on and look under the dash for the flasher that is making the noise,this will show what the signal flasher will look like,then find the signal flasher on the fuse panel under the dash it should be located on the fuse panel.and replace
