I'm not the master of soldering, but I've had a lot of experience after taking it up as a hobby. I would recommend to anyone else trying this to first apply a small amount of flux to the bad solder joint and remove all of the old solder using desoldering braid or a desoldering iron/remover from the area around the pin with the defective soldering joint. Once the area is cooled, clean the area with isopropyl alcohol to prepare it for the repair. When the area is dry, again, apply a small amount of flux to the pin and the area directly next to the pin on the circuit board. Finally, solder the pin back onto the circuit board, preferably using 60/40 tin lead solder. That type of solder is recommended for electronics, as it is less brittle and will last longer. Just remember to be cautious not to inhale the fumes from the solder and wear gloves or wash your hands once the work is completed. Solder containing lead is slightly hazardous and should be used cautiously.

Can you help me diagnose if the BCM might be what's wrong with my 1995 Buick Riviera? The radio will change stations randomly a lot of times and also the volume will go all the way up and I have to manually turn it back down. Also, the climate control/ac temp settings will fluctuate up or down and these things seem to happen a lot of times when I apply the brake pedal. Also, sometimes when I'm driving the climate control/ac will come on by itself. It just started doing this(ac coming on by itself) within the past week and I'm not sure if it only does it when I apply the brake or if it does it randomly. But a lot of these things seem to happen when I'm just starting the car and hit the brake pedal. Does this sound like a bad BCM or just a short/shorts somewhere in the wiring?
a DIY Car Guy (2 дня назад)
it could be either....I'd start with the BCM because that's the easiest

My bcm needed to be replaced, door locks were unblocking/ locking while I was driving and even when the key was in the ignition. Radio light's statred to flicker as well. Drained my battery bought a used bcm for only $50 had someone to program it for $200 problem solved and way cheaper than what the dealership tried to charge me!

Hi "a DIY Car Guy" I have a 2002 Park Avenue - running lights and dash lights go out, and intermittent buzzing under the dash and flickering headlights that kills the battery, then it stops for a while. Does this sound like a "re-solder the BCM" issue to you? (BTW fuses are good) Oh, and please forgive if this sounds like a dumb question, but is the "body control module" (BCM) the same as the "lamp control module" (LCM as listed in the fuse box)?

I'm thinking my BCM is my issue in my suburban. Abs light, parking brake light Service 4wd,service brake system, no blower motor, no cruise, and it doesn't crank sometimes. New ignition switch, new starter, new battery, new water pump, fuses are good. I guess it's worth a shot to look at it. Do you now if a bcm will cause the specific issues I'm having? My windows and radio work fine.
R A (4 месяца назад)
a DIY Car Guy alright. Thank you. I took mine apart just now and there are 2 points, that look burnt up and need to be resoldered
a DIY Car Guy (4 месяца назад)
sounds like the bcm, it causes dash lights to come on, causes no start. It might control the cruise and blower but I'm not sure

This is great info. Now a question for you... have you used this method on any other module? I have a 2003 CTS with a bad roof mount antenna module. This module is responsible for receiving signals from the remotes for door unlock and trunk popper. I am wondering if I can repair it because supposedly my specific module is obsolete and hard to obtain. I also don't want to bring to the Caddy dealer to have them reflash the new module (if i am lucky to find one). Just the reflash will probably cost whatever Caddy labor is for an hour. It's literally less than 5mins to flash with their Tech II Scanner and the closest dealer ship is like 20 miles away from me. Lol

It's always worth a try, I've done it on all kinds of modules...climate controls, relays, cruise controls, etc. Just have to look at the circuit board and see if there are any cracked solder points.
Charley Gripentrog (8 месяцев назад)
No reprogramming. Only when you buy a new one.

Where is the bcm located in a 2004 jeep liberty
James McQueen (10 месяцев назад)
When you install the module after unplugging it to make repairs will the car start and run? Or do you have to reprogram something?
a DIY Car Guy (10 месяцев назад)
you're welcome and best of luck!
James McQueen (10 месяцев назад)
Thanks , I have a 2004 Chrysler Sebring  convertible so I really don't know for sure.  Thanks just the same and God Bless. (Mac)
a DIY Car Guy (10 месяцев назад)
it should start and run, no programming needed as it's already programmed to the car, at least with the escalade this is true

Just fixed my 2004 Nissan Quest BCM - battery was draining and interior lights would not come on. Took apart, re-soldered obviously screwed-up joint - saved $300+ thank you!
Grey Ghost (1 год назад)
Omg. Put some silver solder on the iron before you overheat the board and the joint.
a DIY Car Guy (1 год назад)
lol, it's fine
Roberto Martinez (1 год назад)
bad soldering
Steve (1 год назад)
Not a good idea espically if the relay is bad I did this an it literally smoked my BCM However for around $300 you can get a pre-programmed one from the guys called 1 day auto i believe is their name. Still cheaper than the thousand dollar or more that the dealer will charge to you put in a new bcm an reprogram it.
a DIY Car Guy (1 год назад)
gotcha, thanks
Steve (1 год назад)
Just saying that I tried that method first. The problem is the circuit boards are multi-core boards so heat can damage it. All I am saying is its not for everyone to try it. Believe me I went to a junkyard an grabbed another BCM myself an on this BCM the relay went bad for the power locks this time....Not going to risk pulling the relay off my old an swap it with the bad one on this current board instead i'm going to save the nasty burnt electronic smell in my truck again but just buying a new one already programmed is a safer option. However usually when the relay goes bad it pops/melts the solder due to the heat generated from the relay going bad. My comment is only to educate those willing to give it a try an save the money they do need to know the risk. Mine worked for a week until it smoked I still have the smoked BCM.
a DIY Car Guy (1 год назад)
that makes no sense....you're saying don't attempt to save $300 by fixing something that's already broken...if it burns up it doesn't matter, it was already broken, in most cases it's not going to burn up. additionally, i paid myself by keeping the $300. that's the whole point of my channel lol

can you please tell me where the body control module is on a 2010 Mitsubishi endeavor is at
a DIY Car Guy (1 год назад)
sorry i have no idea...i read in the 04 it's the same as the ecu located in the relay box in the engine bay...can't find anything on 2010

I have a 05 Yukon by the way have you heard of this problem
Travis McDonald (1 год назад)
I'm having issues with my door locks locking and unlocking on their own and my dome light going on And off on its own does that sound like a bcm problem ?
J W (1 год назад)
My impala does exactly same, figure yours out yet?
noah hussey (1 год назад)
Travis McDonald jkkkk
Steve (1 год назад)
Depends on the car as for the Yukon, Tahoe Escalde's yes it is the BCM.
TufRiverboards (1 год назад)
when you repair your bcm, does it still need to be reprogrammed by a gmc dealer?
Charley Gripentrog (8 месяцев назад)
TufRiverboards no
a DIY Car Guy (1 год назад)
It shouldn't, mine did not need to be reprogrammed.

+a DIY Car Guy hey man. can I get a used BCM and use it for my suv. or does it have to be the same # on the BCM
a DIY Car Guy (2 года назад)
+Edwin Castillo you're welcome, good luck!
Edwin Castillo (2 года назад)
Thanks for your help. I appreciate it.
a DIY Car Guy (2 года назад)
+Edwin Castillo ah...all the info I gave you is for the body control module...i'm not sure about the keyless entry module
Edwin Castillo (2 года назад)
+a DIY Car Guy No, it doesn't say that. I just came from Auto Zone and the guy said it is called the Remote Keyless Module.
a DIY Car Guy (2 года назад)
+Edwin Castillo np, the replacement should have the same part number as the old unit. Does it also say "Integrated Body Control" on it? Jw

I am dying of suspense...did that fix the problem?
a DIY Car Guy (2 года назад)
Awesome, it's a very useful skill that you can use throughout your life. For 1500 bucks it's worth getting some practice in and seeing if you can fix it yourself lol. Also they go for about 200 used on ebay. Or I could solder it for about 32.99 lol. I repair climate controls for Preludes regularly and have a repair service listed on my ebay store, if you buy that and send me the BCM I could take care of it. My ebay store link can be found in the links in my channel banner or in the "about" section. Either way, thanks for watching!!
Naomi S (2 года назад)
+a DIY Car Guy I am looking in to learning how to solder. This looks like a handy skill, and I think it would open up a whole new level of DIY for me. The dealership wants to charge $1500 to replace the BCM. Thanks for posting this video, and helping people like me learn about new DIY possibilities.
a DIY Car Guy (2 года назад)
+Naomi S it did fix the problem

Hi sir My escalade 2008 sunroof not working - I tested motor and it turns - the fuse is good... I looked at the sunroof board looks fine. - what do you suggest ?
a DIY Car Guy (2 года назад)
+jay s If the circuit runs through a relay it could be a shot relay, I would also test the sunroof switch with a test light.
