Flickering lights on and off

[Blatalian87]

My 1999 Oldsmobile battery went out the other day as soon as I got a jump my odometer and radio lights started to flicker on and off. So I got a new battery next day and the clicking noise with the flickering lights never stopped. 6 hours later the flickering of the lights stopped but the noise is still there and when I turn off my car the headlights and all the lights in the back of the car flick on and off for 14 to 16 seconds every time. Then shut off. What's the problem. This car is sooooo annoying.

I'd be checking all the battery cables especially the grounds. Need a voltmeter to check battery voltage, static, running. Alternator may be on it's way out.

I just got my battery changed yesterday. Checking the battery cables and the grounds? What does that mean and how do I do that and what am I looking for? And didn't they check the battery voltage,static and running yesterday when I got a new battery? How much does an altinaror cost and can I buy the parts for that and have my friends dad who is a mechanic fix the altinator or do I gotta go to a shop? Sorry so long.

So now its just flickering when I open the doors for about 20 seconds and when I close the hood to my car and the trunk. Almost like the bang is making it flicker. And also I don't have a hazard light button in my car. Wasn't there when I bought it from someone

Sounds to me like maybe it has a theft system activating. Does the horn work and is it also sounding with the lights? Is there and aftermarket theft system/alarm on the car?

It makes a clicking noise like the turning signal is on but isn't on. Yes my horn works, but there isn't any alarm. But sometimes when I get out the car and I lock it before I walk away it makes a noise like I just locked it with a key that has a button. Like u know the sound it makes when u lock it with an automatic key thing. But I only do it manuay cause it didnt come with that kind of key

Definitely check battery connections and alternator output...

"It makes a clicking noise like the turning signal is on but isn't on. "


When it makes that sound, just SLIGHTLY touch the directional lever up or down.....if the noise stops, you need a new multifunction switch.....also, if the your directionals don't work, press the hazard flasher, on then off....if the directionals work now, need a hazard flasher......there was a recall for this....

As GMtech1 asked, check for after market accessories.......

I am not sure of the wiring circuit for this car, but it's also a possibility that you may have a BCM problem....
