#325 of 446 Signal light problems
Jun 22, 2009 (8:19 am)
I have a 2000 chevy Impala and so far has been a fairly good car. However, late last year I started having problems with my signal lights and the hazardous light switch. So i took it to the shop & got the hazardous light button replaced and the signal lights worked fine. However, a couple of months ago my signal lights were not working again and my high beams wouldn't stay on either so, I took it the shop and got the turn signal switch replaced which I believe ,they call it a multi-functional switch and my signal lights were working great. Now my signal lights are not working once again and when I try to turn my signal on it makes a buzzing noise and my airbag light, battery light and brake light comes on. Any clue to what this could possibly be? Be aware that everything else is working on the car. I replaced my battery today and my alternator is just fine being that I got it tested as well. Any suggestions are greatly appreciated being that every trip to the shop is at least 350+.

I had to replace the hazard switch on my Impala 2000. I did not have any of the other problems you mention. Could it be possible you got a bad switch? It might be worth replacing it again. To save money you can do it yourself. I have step by step instructions on Flickr:
The air bag light etc might be due to the bad switch. I seem to recall something odd that the signals are on the same circuit as the airbag sensor.

The hazard switch is GM part #10359031. Costs about $45.

I posted earlier about replacing my BCM because the car wouldn't start. Then the very next day, the car wouldn't start! Dealership said it needed a new battery.
Anyway, went in this a.m. to talk to the service manager and he sold us a battery at a discounted price of $59.99 and didn't charge anything for installation/labor. Hopefully, all problems are solved

Does anyone happen to have step by step instuctions on how to open the steering column in order to replace the turn signal switch. Its called a multi-functional switch but it is the switch you use to turn your signals on and off and for your high beam as well. So it is the the lever that comes off of your steering column on the left hand side, NOT the hazardous button switch. Im needing to replace turn signal lever so anyones instructions are appreciated....Thanks in advance......

My interior rear view mirror went up in smoke one day, and since that time I've had a never ending battle with my lighting system. There are 5 wires going to the mirror. The mirror has a left and right reading light, a sensor aimed at the rear window to automatically dim the mirror, and another pointing straight ahead on the front of the mirror.
I found a used but good mirror, replaced it, and it works great. But, to have high beams, I must hold the dimmer switch up manually else they go out again. My DRL (daytime running lights) will work only after I rigged a 12 V
bulb over the ambient light sensor on top of the dash. It's located in the drivers side defroster grille. Naturally the box must be sealed so as not to hinder your night time vision, but with small airholes to disperse the heat from the bulb. I was told that the BCM was good if I heard the chimes for different events on the car, I do hear the chimes. Man, I need help. Thanking you in advance,

Chevy (Impala) has a very poorly designed plug on the back of the interior rear view mirror, it seems very loose.
Try (gently) wiggling that plug during the time when your problem arises. I had a very similar problem with my 2005 Impala.
My sensor that darkens the rear view mirror (from cars behind me) wouldn't work, nor would the reading lights in the mirror itself. To this day I have a small, hidden, plastic tie holding the wires to the mirror, snug against the arm for the mirror, it's now working fine.

I am having the same problem with my signal lights not working and buzzing with the same dash warning lights going off although I am also not able to start the car at times and the computer shuts down the car on its own. the only way to start my car is to put it in neutral and start it. I'm eager to see what responses you get...Please also keep me informed if you learn something new to do and or how to replace the signal switch. Thank you.

Blinking dash board lights and buzzing is probably a defective BCM.
The turn signals not working could be a defective turn signal combination switch or a defective hazard button switch. If the turn signals start working once you push the hazard button, that would indicate a short in the Hazard switch. If you check one of the earlier postings, someone actually put a link showing how to replace the hazard switch.
