2001 Chevy Impala rear brake lights are not working. I do have the 3rd brake lights. All of the bulbs are good. I bypassed stop light switch and have replaced turn signal switch. I have checked the connections and they seem ok. Could the four way flasher switch be bad ?? Turn signals do work fine.
Did you check all the fuses? Just need to be sure since that is the first step in diagnosing any electrical problem on today’s cars and trucks. If the 3rd light works, then the switch is good.
Yes i did. I’m pretty much at a loss – I was an auto mechanic for many years and am not very often at a loss.
OK. The you are going to have to check for power and ground at the rear sockets to which one you are missing.
How can that be a problem if the rear turn signals are working ?
What happens with turn signals on and then hit brake pedal? What do the signals do?
They work normally.
Hmm. Well without a schematic in front of me, that is a tough one. Yes, they do go through the hazard switch. Try pressing it when the t-signals are on. Very slowly to see if they start to work.
They work normal 4 ways over ride the t/s and no brake lights.
OK. Again, without a schematic, i don’t think i can be much help with this one right now. There are a few connectors that would need to be checked for power to narrow it down. If you would like to leave me your email, i will ge a schematic later today and give some things to check.
I’ll keep on checking and let you know what I find, thanks. I will find the problem. Now it’s a challange.
2000 Chevy Impala Check Engine Light
I have a 2000 Impala 3.4L V6 the check engine light keeps coming on I have had the engine check and no problems so they shut the engine light off. My neighbor told me it was a heat sensor when I called the auto part store they told me there is no heat sensor What would keep the engine light coming on. Please help me if you can.
Do you know the code number they got out of the computer? That is really the only way to be sure what system is having a problem. Any time the check engine light is, or was on, there will be a trouble code stored in the computer memory.
No I don’t.
Well, without the number, it would be a guess. I might assume they were talking about an ogygen sensor heater control circuit, but without the number i cannot be sure. There is no part called a heat sensor.
If I have him check it and scan it tonight will it show a code even if the light is off? Could we get a number even if the light is off.
If they cleared the check engine light code, then no. The code would be gone for good.
Ok thank you for your help
