Question about 1998 Buick Century

1 Answer

Cant resolve a blinker issue, Tried the easy stuff.

This one has me wondering. The left blinkers all work fine, in dash and outside.. Problems, Right turn signal on dash does not light up at all, front right blinker does not work. back right blinker works but its blinking fast. Hazards also dont work on the front right blinker but all others work fine. also when the hazards are on the dash light still only works on the left and the flasher sounds normal. I can hear the flasher going normal on left sinal, fast on right. This is what I've done, replaced flasher, replaced all bulbs with correct new ones. replaced entire front right light assembly and cleaned ground (I think it was the right ground was located near top of radiator) What else could this be-Please help.

The signal wire going to the right front has a splice for the dash indicator, a wire branching off from the turn wire and going to the dash. It sounds like that right signal wire is broken or lost a connection before it splices off to the dash, so the problem sounds like it is under the dash, either coming out of the turn signal switch to the flasher or from the flasher to that splice. You may need a multi-meter to check voltages on that wire at various places under the dash. Ascertain which color wire you need to concentrate on. Check for voltage on it with key on and right blinker on-voltmeter will spike to battery voltage, then fall to zero as the flasher breaks voltage continuously, if checked after the flasher. If checked when leaving the turn switch, it should be a continuous signal on that wire. Think you better find a wiring diagram to find the right wire to check. Good luck.

Hello,
I know it sounds strange but I would first check the bulbs and then check the hazard switch. The hazard switch is also the flasher unit. It fails and there are alot of stsange sinarios.

I hope this helps,
Roy

My left blinker blinks very slowly and wont blink at all with headlights on, right one works fine. Also green turn arrow lights on dash when you turn on headlights?????


It is hard to say for certain without knowing the year, make, and model of the vehicle, but I would look for wiring problems in the steering column and blinker switch, especially if the headlights and blinkers are both controlled from that location.

Right blinker makes both back blinkers flash but only the right on the front


I would suspect the turn signal switch is defective. Do not place any parts until an qualified GM tech has confirmed this guess.

Blinker, cruise issues...electrical?


The problem is caused by the emergency flasher unit. This is a common problem and you can find a few youtube demos on replacing it. I did it in about 30 mins. I don't remember the cost but it was stocked at my local chevy dealership.
good luck.

that vehicle has a desperate relay for the hazards which is why they work, you have a defective signal flasher sometimes called a signal relay, follow the noise to locate exactly where the part is, usually under driver side of dash, it is a very cheap part and easy to install.

The right blinker issue sounds like you have one bulb out either front or rear check them both. The left blinker issue sounds like either bulbs(both out) or fuse, or worst case blinker switch has gone bad on left turn only so not picking up the signal.

Saturn 2002 VUE Turn Signal not working properly.


You need to check your left side turn/park lamp bulbs for correct part # & installation.If that checks out you deffinetely have a ground problem.When you have other lights blinking with you turn signals you have either a bulb incorrect or a bad/poor ground.If bulbs check out check your forward lamp harness ground.Hope this helps
