- Repairing the Body Control Module on my 2000 Camaro Z28. The video is a little long but I wanted to show the steps I went through to fix it and give as much detail as possible to help anyone that runs it this problem! This seems to be a common problem on the 4th gen F-body's.
If your factory radio cuts out and the windows stop working it's most likely the BCM.

So thankful for this video! I couldn't find anyone else who showed the process of actually removing the silly thing, which was the hardest part. I never would have figured out that you just have to bend the plastic that far to get it loose. I was able to fix my intermittent radio and windows for free which was super satisfying.
Glad it was helpful. That's one reason I made it so detailed and long, to show everything you have to do and go through to fix it. Thanks again for watching....
a repair like this cost thousands of dollars and this guy if this video halps me repair it I will be forever greatful This damn Voyager has been one electrical headache after another
yes that is awsome. I hope to have that luck with mine. the only thing that works on my van is the engine. everything else is dead. I think it is easier to rmove my engine then to take this god awful BCM out! Chrysler sure went to alot of trouble to prevent owners from repairing their own cars. I hope those engineers rot in hell! I think i will have to buy a remote snake camera to find all the damn bolts holding this damn silly thing in! How did you ever expose the unit like that? I removed the knee block metal plate and anything else I could remove, and still cant see the top of it. but my van is a 98 voyager so maybe that is why?
Soldering not being one of your strong suits was an understatement. I know it is an old video but for those looking for info the proper way to solder is to flood the joint with flux, apply heat to the joint with the proper soldering iron ( not a torch, not a gun but but rather a 40 or 60 watt pencil) then apply the solder to the joint once it is molten. Never carry solder to the joint with the iron.
Thanks for the tips!
Always looking to learn more
Just did this tonight. Took longer to pull the damn thing out then it did to figure out my soldering iron was shot, drive to the store, get a new soldering iron and solder, do the job, clean up, and retape the box. Seriously though, great video and info.
Glad it helped and thanks for watching.
I'm gonna try this on the bcm in my 2007 chevy malibu. Costs an arm n leg for a new one n more to get it programd by dealer or smone who got knowhow n tech gear. So thnx for your video!
Nice work. Only thing I would suggest is using a solder sucker and removing their original lead-free solder before adding quality leaded. Stuff is terrible for heavier, unsupported components like those relays... 👍
As a former electrical/mechanical technician in the electronics industry and former Master Trainer that certified companies employees to IPC standards for soldering and cable harness building, you are 100% correct! Lead Free is more brittle and prone to tin whiskers. A couple of the downside to lead free.
Only class 3 medical, aerospace and military applications allow the use of leaded solder. But when using lead free there are mitigations that can be used to protect lead free joints but most class 2 & class 1 products don’t often use them.
My only recommendation on top of this information is to always disconnect your battery before doing any electrical work in your car, especially if removing components such as radio, ECU and BCM.
THANKS ALOT FOR THIS VIDEO BRO...
I just did this today on my 2001 Camaro, had the same issue going on for a long time with the windows and radio cutting out...This video was very detailed and very helpful...Once Again thanks bro and God bless you...

Thank you so very much for your video. My 98 Trans Am windows and radio is working great now.
I'm glad it helped. Please give it a like if you haven't and check out some of my other videos.
Thanks for watching
@@437MotorsportsandOutdoors absolutely!
That's a great job buddy saved you time and money congrats
a bit of cracked solder can make you absolutely crazy - ugh. Good job!
Thanks for watching
Just got mine done after 7 years of suffering with that problem
@MurderGang803 you could pull the plastic cover from under the Dash/glove box using a trim removal tool and tap on the BCM with the key switched back to make sure that's the problem.
Hope this helps you!
Thanks for watching and don't forget to Subscribe, Like and Share . Have a great day.
did that sole your issue long term? going to give this a shot in my 04 sierra. GM plastic and solder from the 90s and 00s were total crap.
It seems to have fixed for me.
Hopefully it works for your application as well.
Thanks for watching!
that makes sense. those solder joints are holding heavy componants
high stress on solder joints
It is common sense to bolt heavy hardware down. Look at any board manufactured for the government. you will see that all havy componants with stress on them are bolted down... conectors, large capacitors, transformers etc
Yeah that would be my guess!
When mine was acting up, it would do it in all the switch positions. The radio and the windows would not work. If yours only does it while the switch is back then it could be your switch it's self.
437 Motorsports no my switch is good just that my body control module is Burnt
@@murdergang8038 Ok, then this I believe should fix it.
My 99 z28 just encountered this problem today of my windows and radio and power convertible top stopped working. I got the driver window to go down but now it won't go up. And the radio will try to come on so when it does I try to put the window up and the radio shuts off immediately and nothing is working :(
This could possibly fix the problem, but no guarantee
I would wait 6 months (if thats your car) to put the BCM back perminantly and thouroghly test it before a perminant installation. I had to do this 5 times to my instrument cluster on my 98 Plymouth Voyager
No sir. Everybody else does not remove clips from wiring harnesses quickly and easily.
That only happens in UA-cam videos.
IMO, wiring harnesses are the worst, most frustrating thing about car repair.
that thin copper bus wire must be a WiFi antenna.... hmmm to communicate with the key? remote entry?
One of my buddies came over the other night and soldered my BCM for me and my windows and radio don't cut out anymore but now my security light is staying lit after I start the car and goes out after a couple minutes of driving lol :( fix 1 problem and now another pops up!!
Well at least the windows and radio are working! Lol
Hopefully the security light works it self out
Just bought a 1999 v6 not running. Its been at the dealership for a month now they said that the bcm is shot. Going to send it in to get repaired at $300. Paid $1,600 for the car. $500 for repairs and $300 for the bcm repair.
That's still not a bad investment if it's up and running.
But it's definitely cheaper to do it yourself, if you're able to.
Gracias por tus buenos videos maestro 👍
Appreciate that
I am restoring a 66 Cyclone to drive I am sick of all the BS in these new cars. Way to much useless stuff in these new cars. The simpler the better.

@@rogerd4559 hopefully it is similar and does the trick for you. Thanks for checking out the video.
Same thing happened to me today when I was driving To my job the radio kept on turning on and off on my Firebird
Mine is still working after the fix.
Thanks for watching and Subscribe if you haven't.
@@437MotorsportsandOutdoors I'm going to see if I could take it to a place to fix it for me cause I am not that good as sottering
dont dab solder on it is not glue. try remelting the solder joints and use a good flux then thouroughly flush the residue off with alcohol or a flux remover as that residue will collect dirt in a year and cause all kinds of shorting problems
Do you think a bad BCM also causes the gauges to also stop working too or this issue is solely for the windows and radio ?
I personally only had issues with the radio and windows. I wish I had a answer for you about the gauges but unfortunately I'm not sure if it would affect them.
Yes absolutely yes that's one of the symptoms of a bad bcm
@@panzerwaffen2873 thanks for the response man, now I know what to replace for all these troubles
@@gravelord2600 no problem boss man here to help ... I'm having issues with the bcm also ... 2005 corvette ..even more difficult cause some people don't want to put their hands on it besides everything and when I say everything I really mean it ... Is electric .. trunk release... Gas cap ...etc every component is electric
@@gravelord2600 what car you have ?? Or at least what's the one you are having issues
did you have to re program the bcm after disconnecting and repair ?
I didn't, just plugged it back in
@@437MotorsportsandOutdoors cool thanks , so was it under dash /glove compartment along side the air con motor ?
@@niecylee7404 Yeah
Is it possible to do this job without removing the kick panel? It looks pretty out of the way...
It may be possible, it's been so long I don't remember if I tried to get to it without removing the kick panel.
Great video Thanks
Thanks for watching.
if I swapped in a different BCM from a different car same model , would that work?
or would I have to program it or something?
thanks
I'm not 100% sure if you can just swap the BCM's. Beings I believe it works with the security system so a different one mite have to be programmed to work with your car security system! I would do more research on it.
I only looked at how I could fix it myself to save myself money.
437 Motorsports
Thanks for the reply , I found what told me I would have to get it programmed, if you ever need to it wouldn't hurt to try it , maybe there's some models where you can just swap em in .
Thanks for the time
@@larrywebb8309 No problem and thanks for checking out my video. If you don't mind Subscribe, Like and share.
it is a chance you have to take. Do both vehicles have the same exact features? motor displacement? same power windows? accessories daytime running lights wiper delay, AC?
@@rogerd4559 its matched to your vin
Good job, made it look easy, always wanted to do that, open BCM, or TCM, and see, if I can find bad soldier points! By the way, did this fix all problems???, And one more question: Are you in upstate New York? That house look like I been there.....many years ago????;o)
I've had no problems with the problems it caused ( windows and radio not working ) since I re soldered it it and I'm in VA
@@437MotorsportsandOutdoors OK, thanks=) Merry Christmas!!
@@Eeropolvasti Merry Christmas to you as well.
Thank you so much
Glad it helped!
Great video and very informative..! I have a 2007 ext Cadillac..any chance that you can tell me why my backup/reverse lights stay on? I replaced the brake switch on the brake pedal...someone said the relay to the backup/reverse lights burned out in the ON position but I cant find the relay... someone else said the relay is in that BCM box that you were working on..?
Could be the switch in the trans or maybe a short in the wiring . That's where I'd start . Mite need to get wiring schematics
Did you figure out your problem? I’m having the same issue. I’m thinking it’s the bcm
@@things971 no I did not... however here in Tx you don't gave to have reverse lights to pass the state inspection.. so I just pulled the fuse and never looked back
Last night, the brake lights and reverse lights were going off like Christmas lights lol I don’t wanna start throwing parts at it without doing any research. I guess I’ll start from the bcm.
@@things971 yes that's where I would start too... I think I saw a video of someone saying the same thing about their Silverado
My is a satum the widows are ok the door are ok but the remote can not open the door or look the because of that the car cannot sater wat can I door this not the first time wen it works the car will
I have no experience with the car you mentioned. So I can't give any useful advise, sorry!
I have a 2002 Camaro SS and the driver window works but the passenger side doesn’t work at all. The radio cuts in and out sometimes too. Also, the power locks don’t work at all... Could all that be the BCM?
It's kinda odd that the drive side works but I believe that the BCM could have something to do with it. Only I know to check is to pull the panel down under glove box and wiggle and move the wires go in to the BCM that tell is that is the cause. I could wiggle mine and everything would work until it lost connection again.
Hope this helps and thanks for checking out the video.
Yes sir
hello my car dont detect the keyles control
!! ist same this problem?
I'm not sure, you'd have to do more research on it.
Hey bruh, after repairing the module, reconnected and about running it for 15 mins the electronics was still running but the engine stopped working. And then 5 mins later everything died down. No electronics, won’t turn over, if I remove the key the alarm goes off. Any solutions? Or tips what’s going on???
I wish I knew bud, this isn't something I've ran into personally.
I'd check all my fuses and pull the BCM back out and look it over for any other cracked solder joints. Other than that I'm not sure.
next video , put a magnafying glass in fron of the camera lense that works for me
The funny thing is.sometimes after a repair They don’t stop working again until u install it back and button up the panels and go for a drive😂😂😂😜 I’ve had a few that the harness is so stiff and crammed that it rebreaks the soldier joints from the weight of the harness and the vibrations of rough roads
Good info, lucky so far mine has been doing well.
437 Motorsports yea my 98 firebirds bcm is doing good so far as well been over a year since the repair but thanks for posting the video! Have a great day😁
yes Ive had that too with my instrument cluster. It is because of poor design and expecting a solder joint to support heavy loads
and with all the pulling pushing on a connector on a board like that, it cracks the solder joint over again. a properly made board will have screws to mount that connector and the solder joints just make a complete electrical path to the circuit not support the connector
jim halcom 100% correct and yes they should have had the harness screwed to the circuit board. Or hadn’t mini harness coming off the bcm to connect to the harness to lessen the load or stress in the soldier joints.
Have had*
My issue is that my car won't turn off. Also, the cluster lights are all on even when I plug the battery. The power locks, windows, ac and so on do not work. Once I turn the key to turn off the car, the car stays on and the cluster lights also stay on. The only way to turn off the car is to remove the Main relay and remove the ground battery or else it will drain it. I can't find anybody to help me. I've replaced the ignition coil and it didn't help. I don't know what else to do. I'm hoping is the BCM .
I wish I had a definite answer for you, but unfortunately this is something I haven't dealt with personally. I can check with my mechanic friend and see if he'd have any idea what to look at.
So his advice is to take to a shop and have them do a proper diag of the electrical system. That's the only way to pin point the issue. Hope this helps and thanks for watching.
What year is please
My car is a 2000 Chevrolet CamaroZ28 , should work for the 98-02 also I would think.
Same problem but....my windows still work, radio doesn't...radio fuse is not blown. Still BCM?
Not 100% sure on that. I would check voltage at different points though out the radio circuit. Check fuse panel under hood if you haven't already. Radio might have just died . Those are the things I would look at before pulling the BCM. Hope this helps
@@437MotorsportsandOutdoors Actually, as of today, windows aren't working now...and hatch won't pop open. 🤔 But oddly enough, windows were working when radio was out yesterday.
@@zambino8763 Might be worth taking a look at BCM then .
@@437MotorsportsandOutdoors I'll report back with results. As of now, passenger window will go down. The other items mentioned are not working. I just need the hatch popped as of now, so I can work on some things...but I get stuck trying to squeeze back there to try manually. 😂
@@437MotorsportsandOutdoors Wow. After fighting, struggling, and beating my brains out...I find out that the 94 Firebird Formula did not have a BCM. 😂🤦♂️
My latest findings are that the hatch is getting power to and from the relay (it's clicking) but no power to the actuator. Radio still not working. Driver window bot working...but switch may be bad. Power locks move in 3's. Weird. Meaning - the door lock slider moves 1/3 open at a time.
Why didn't you restart the car?
I never had a problem starting it.
The BCM only stopped the radio and windows from working.
You didn't describe the original symptoms.
Radio and Windows stop working randomly and then all together.
What was the error codes ?
Mine didn't have any codes. The windows and the radio just stopped working one day when I got in my car after work. The problem would come and go, I pulled the panel user the dash so I could wiggle the BCM to make the windows work till I had time to do the repair.
Ok thanks mine have the EPC when I am driving and be in limpo mode VW polo round light 9n I thought maybe is something like that
