Check the turn signal flasher way up under the dash, also check the fuse box in the engine compartment. Electrical problems are charged by the hour and the tech gets a minimum of 2 hours. Anywhere from $75.00 to $150.00 an hour. My son is a mechanic and he says electrical problems are the hardest to find.

Engine compartment and cab fuse panels all show good.
I can't find the flasher box. I've damn near torn the dash out looking for it. Hell, it's not even behind the ABS brain box. |

Sounds like she is out of blinker fluid
 Seriously... check for voltage/ current if you have a multimeter, if that's the case start looking for a wire that has become stripped and is grounding out somewhere. IANAM but I have had similar problems in the past with other cars. |

Doubt seriously that it is a problem with the flasher. My guess is a bad ground or an open wire. Look at the harness in the trunk.

Used to be that if the tail lights weren't working the dash lights wouldn't either. I don't know if it was designed that way on purpose to let you know something was wrong or just coincedence. If its tail lights and flashers it could be a dual filiment bulb out or the flasher unit. Listen for the flasher to click. If it clicks then it's working.
Didn't we have this topic last week? |

in the repair manual the flasher is located on a bracket above the brake pedal

Check continuity of the fuses with a meter. I have seen more than one that looked good, but was blown.
Plus, the circuits you say are down all operate from the switch assembly on the steering column. After the fuse check, I would look at that assembly real hard. |

TAIL lights are a separate fuse from STOP & TURN lights. Do the 4 ways work?
Turn signal switch in the column does NOT affect TAIL lights, only STOP & TURN. Bulbs or grounds on the sockets are possible offenders. A simple VOM is trhe only practical way to troubleshoot these things! Were a wire shorted a fuse would be blown. Only common wire to TAIL and STOP is lamp socket ground. STOP & TURN is a different story as both are the high intensity filament in the bulb and use the same wire. FLASHER has no effect on TAIL or STOP. |

You have a bulb problem, and it might not be visible... Get a multitester, and check the bulbs for continuity... |

Many times when there are multiple problems involving the lights you will find them to be related to a faulty multifunction switch......

There is a multi function switch assembly that chevy uses that does allow one assembly to affect tail lights and stop&turn as well. Not only that, but the damn washer/wiper, cruise and high beam H/L switch are also co-located there as well. |

Amen AR-Wrench. Not a bulb problem when all rear bulbs don't work. I'm on the road and don't have access to the wiring diagram. |

If by tail lights you mean Brake lights I'd say it sounds like a turn signal switch , not that uncommon on a GM of that age . Only problem is that its a multi function and you cant replace one side .

I've a VOM (Fluke 77), fuses all show less than 1 Ohm each. This is true even when I pull them out of the panel.
The tail lights (that turn on in conjunction with the head lights) work. The Stop lights and the Blinkers do not work. Back up light works. I've not check the 4-ways yet. No "Clicky-clicky" when I turn on the turn signal, no flashing indicator on the dash. Just dead, like I didn't even turn them on. When she gets home, I'll try to get up under the foot pedal to see the flasher can. I could get to the switch, but didn't see the can up there. Her other car is an Acura. Good car, just not four doors, and the manual transmission's clutch kills her already injured back. As soon as I get some time, I'm going to sell off this POS Chevy and the Acura and buy her a van or SUV. Maybe a Subaru. Just depends on what kind of deal I can get. I won't buy new, so I'll search for a while. |

OK, this car is on it's last ropes.
I just went and checked everything again. Still, no blinkers, no brake lights. Then I checked the four way flasher, and they worked. Immediately the blinkers and tail lights started to work again..... I'm thinking there is something in the 4 way switch that might be throwing it off. |

you are getting somewhere, electrical problems are a proccess of elimination. inspect the 4 way switch plug where it plugs into the vehicle harness. over time vibration, oxidation and overcurrent can cause these problems. schematic would help. Sorry, I'm better at finding than explaining.

test orange lead at brake pedal switch for +12V, if it's good, Check the white wire at the brake pedal switch it should go +12V when pedal is pressed, if it does, test again at rear brake lamp assembly, if you have it testing at the lamp, do a continuity test from the outside of the bulb to chassis ground to see if there is indeed ground present, if not you will need the schematic to determine where the groung point is, or just ghetto-rig your own ground.

Check the hi low beam switch should be under or around the steering column i had the same problem on an oldsmobile it was the hi low beam switch.

DING DING DING, I bet you got a bad ground. Wait till you turn on the radio and the Winshield wiper fluid starts pooring out. Happened to me on a '94 Oldsmobile Bravada. |

We are starting to get down to it; NOT TAIL lights...... 4 way proves wiring to rear, lamps, grounds, no shorts etc. STOP & TURN coming back after pushing 4 way switch tells me it is dirty contacts in the 4 way sw. Operate it several times and the problem MAY be gone for months or longer. Those are a PIA to change for a driveway mechanic.

The emergency flashers are on a different flasher unit than the blinkers.
I'm betting on the turnsignal flasher being bad. |

bad bulbs usually give you a very fast blink due to the lowered resistance in the circuit

+1 for bad flasher unit. They look just like a little round drum, about 1" high and 1" wide. They plug right in and wear out all the time on GM cars.
