When I had my BCM replaced back in 2005, the dealer charged me about $400.00. I contacted Chevy Customer service because the care was less then 3 years old but I just exceeded the 36k mileage warranty. Chevy agreed to reimberse me for half the cost.
My 02 Impala is a lemon, and from the posts that I am reading about the newer models, Chevy is still growing more lemons at the factory! :lemon:
Does anyone else have this problem? :confuse:
I just had a total tranny rebuild in which my car was good for a week, now my gauges have went haywire and the engine is cutting out and it sounds like the door locks are being locked/unlocked. Has anyone any idea what this could be?
The engine cutting out could possibly be a crankshaft position sensor. I would start with a code reader and see what you get. :confuse:
I am having a crazy and potentially dangerous problem. It started with me driving down the road, about 50 miles an hour, and my dash lights all flash on. My gauges drop to nothing. My message center first displays the red "battery" light, then shows nothing. My power steering shuts off, ABS doesn't work, and I throw it in neutral as I coast to the side of the road. I stop, throw it in "Park", and turn the key off. Wait a second, then turn my key to "On" and wait until I hear my fuel pump cycle and everything resets itself. Turn the key, starts right up like it never happened. No evidence of the incident remains, not even the "Check Engine" light. This will not happen on my 47 mile commute in to work, yet on my ride home it could happen 1-8 times, maybe more if I have to go further.
I took it to the shop, no codes show and of course it doesn't happen when they're in the car. They replaced the TPS sensor. The 30 mile ride home from the shop (at 2pm), no incidents. 4 days later, 47 mile ride in to work (6am), no problem. Ride home from work (6:30pm) shuts off exactly like before, 3 separate times.
Today, shut down 3 times exactly like before, the 4th time the entire dash flat-lined, all gauges, the P R N D 3 2 1 shift icons, shut off. The only light remaining belonged to my odometer. The car was still driving. Engine never shut off, ran fine for 5 miles with no dash activity (aside from the odmeter still rolling) and shut off totally like before.
My Impala has a V6, 3.6 engine. I put in the (barely 3 month old) battery from my '00, so I've already done that. The TPS sensor. I have heard of a "Crank Sensor" that may be the culprit. Also the "BCM".
I know this is a lot of information, but I hope to cover all the bases. I'm not looking for alternator, starter, or an actual engine mechanical suggestion. With the research I have put into this issue, I'm leaning towards electrical/sensor/computer issue.
I loved my '00, and I'm not willing to complain about how awful these cars are. I've had nothing but good luck with the Impala brand. My '00 had a few electrical 'ghosts' as well-the turn signal only worked if I pushed slightly on the hazard switch, I had to remove the stock stereo because it would cycle (with no disc) until my battery died. Those issues were easy to overlook when compared to never having to replace anything mechanical (aside from normal wear-and-tear) for almost 10 years. I am a die-hard Impala lover, for better or for worse.
So please, anyone with any suggestions, please reply. I want to make sure I do as much research as possible before I start a trek that could be very expensive. Thank you for reading through this long post, I am open to any suggestions.
Your best bet is to have the dealer diagnose this. If the BCM needs replacement you are probably looking at $500-600 dollars. Unfortunately you can not replace this yourself because it requires special programing that involves a computer and typing in your VIN #.
Good luck! Other common problems for this model vehicle is defective high/low beam combination switch. Faulty Passlock sensors, Noisey ISS shaft in steering columnn, intake manifold gasket leaks, and recall on cat converter. Other than that it is a smooth riding car! :sick:
It runs perfectly fine, until the temperature reaches about 25 degrees Celsius.
Then the ticking happens. There was a ticking on the passenger side, which would cause my cabin lights to flicker. But I figured out that it was the battery relay in the panel.
But there is still a ticking and if feels like it is coming out of the steering column. I can feel it in my steering wheel when i have my hands on it.
That ticking causes my radio to not work. a message shows up saying cal error and then locked. Also, my running lights flicker unless i turn my headlights on, then it stops and when i am driving there is a loud tick unless i put my foot on the break. And the biggest problem this causes is that my fan to cool my engine stops working, and i need to drive at least 60 km/h to keep if from overheating. If i am stuck in traffic on a hot summer day my car will over heat.
I hope someone knows how to solve this problem !!
Based on your experiences can you give me any ideas?
After buying the car, the car needed a jump to start. I bought a new battery, when the mechanic tested the battery he said it had a bad cell, i figured cool 1 problem down.... HA.
So, the next day she starts up dandy. I went to the bank to cash a check, literally in and out, i try to start the car but its dead. wtf. My friend comes and gives me a Jump and charges the battery for a couple minutes, i was then driving to the post office and she starts over heating?? The battery light flashes on & off on the message board, And the red hot coolant starts flashing as well. I Immediately pull over and open the hood to find some smoke but not a lot.. There was also a very loud clanking sound after i shut the car off.. It lasts a few minutes then stops, i eventually found where it was coming from, a cooling fan, not sure which one but i saw it turning and hitting the car. I let the car cool off, jump it and take it to the shop again for a coolant flush and alternator. Still dies and overheats, I'm thinking it has something to do with the wiring the past owners did? Or if maybe a jump blew a fuse or cable.. maybe a power surge through the car? Not sure what's going on here... going to get a free diagnostic and quote hopefully saturday. Every thought helps [=
Is this an issue with the BCM? Or is it related to the battery?
Any information would be much appreciated!
Thank you
Have '02 Impala, 6c, auto. Periodically, when using turn signal, there is a buzzing noise, the airbag light blinks and the door locks will open and close Ignition switch? Today, I can't start it. Electrics work (radio, lights, gauges) Battery OK, as is gen and start. ??????
Same probs, flashing lights, outside & inside. the clicking noise was from the Battery Run down Protection Relay, when I took it out it was hotter than hell. still did the flashing and stuff butt the click was gone. If you pull the 10 fuse next to the Starter Relay on the driver's side, wait 2 or 3 minutes and push it back in, it seem to reset itself and the car would work for a few days. Thought it was the Starter Relay but wasn't. You can use the Rear Defog Relay from the passenger side and swap it with the Starter relay to test because they are the same relay. So now I am getting a Battery Run Down Protection Relay and hope it's that and not the BCM, which will be next if this don't work. Hope this helps someone! =D
The body computer is the module that recieves and confirms the identity and commands from the key fobs via the RCDLR.
So I'm having like the same issue as everyone else mine is an 03 impala but as soon as I start my car it will run fine for a few miles then out of no where my lights start flickering my locks start locking and unlocking my check engine light comes on my abs light comes on and then my battery light starts going off all while my car is driving. Scared the crap out of me I was on the freeway doing 70 when it happened thought my car was going to brake down bought a code reader and of course dam car isn't throwing any codes idk what the issue is but would like to get some ideas before spending out the butt for putting my car in a shop?
