VEHICLE RELAYS Operation Diagnosis
Turn Signal Lamps
The HAZ LP fuse in the underhood fuse block supplies battery positive voltage to the multifunction hazard switch assembly. The TURN fuse in the IP fuse block supplies Ignition positive voltage to the multifunction turn signal switch assembly. With the ignition switch in the RUN or START position, ignition positive voltage is connected through the multifunction turn signal and hazard switch assembly to the flasher module which is grounded at G205. When the turn signal switch is placed in either the left or right position, the circuit is complete from the flasher module to the turn signal lamps and to ground. 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 activated, all turn signal lamps will flash including both IPC turn indicators. The front turn signals are grounded at G111 and G112. The rear turn signals are grounded at G475 and G422 on the pickup and G450 on the utility.

My left turn signal recently stopped working. Before ceasing to work, the turn signal (just the left) would blink very rapidly (machine gun speed).


sounds like one of light bulbs was malfunctioning and caused the flasher unit to blink rapidly and iy burned out. Replace front and rear turn lite bulbs and see if flasher flashes. if not check fuse and replace fuse. If fuse okay replace flasher unit. Good luck

My turn signals sometimes will quit working then I have to hit the hazard lights button leave it on and then turn my turn signals on then they work what causes this to happen


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.

Turn signals wont work but flasher an lights come on


If the hazard flasher is working but the turn signals aren't, the problem is most likely either fuse A11 or the #2 relay in the trunk fuse block. However, if these check out, the problem could be either the turn/hazard switch assembly or the turn flasher module.

If both the turn signals and hazard flasher are not working, the most likely problem is the turn/hazard switch assembly.

Where is on 1987 pontiac 6000 are the bulbs for turn signals How do I get to them? & or the flasher ? Is it in the fuse box?


The turn signals at the rear share the same bulb, same filament on the bulb even, as the brake lights. So if you have brake lights, the rear turn signal bulbs are good. If I recall, you access the rear bulbs from inside the trunk, and pretty easy to change bulbs. Look for a panel or trim piece in the trunk that covers the light bulb assemblies. You turn the bulb sockets a quarter turn counter-clockwise and pull them out, then you can replace the bulbs. They are two filament bulbs-one filament for the park lights (tail lights) and one filament that serves for brakes and turn signals together.
The flasher unit is a small round cylinder, I don't believe it was in the fuse box, but located up under the dash, close to the steering column. The hazard flasher unit was also up under there and looks the same. Look for them on a bracket near or by the steering column, possibly one on each side of the steering column To find the turn flasher, turn your hazard switch on. The little round unit that is clicking-you may hear it or feel it click with your finger on it-is the hazard flasher. The turn flasher will be the one that is not clicking. A little round cylinder is how you identify it.

1997 Chevy Tahoe both turn signals stopped working


Sounds like the flasher unit to me. Normally the emergency flasher and turn signal are separate.

Turn signals dont work headlights dont dim heater fan doesnt work


Did all these problems happen all at one time?? If so you may have a bad body ground. Try running a electrical wire from the (-) negative side of the battery to the body and see if this works. Be sure this wire is to a place with no paint as low voltage electricity will not flow through paint.
A). If not try replacing the turn signal flasher for the turn signal problem. This is usually the culprit and it's easiest and cheapest to replace. The turn signal flasher will be found under the driver side dash next to the hazard flasher. Turn the hazard flasher one to locate it. If you want try swapping the turn signal flasher with the hazard flasher to see if this fixes it. They are the same style flasher.
If this doesn't work you may a faulty turn signal switch or some wiring issues.
B). It could as simple as the head lights bulbs need to be replaced, it's rare but I have seen when both bulbs blew at or near the same time. If your able check the voltage at the head sockets.
C). Could be a bad blower motor or switch. I'm not sure if these models have a resistor block or not. The resister block controls the electrical current going to blower motor which controls the speed of the blower fan.
