No the BCM will not cause a dead battery, are you sure the battery didn't just fail, they just go open on these new design sealed units, one day crank fine the next nothing, see it all the time, in fact 100's of times over the years on sealed batteries no matter who makes them.

Chevy Uplander 2005 electrical problems


This sounds like a typical BCM (body control module) problem. First thing would be to check the fuses. Pull them and visually check for bad ones. You'll know when you see one. Doing it this way lets you know if they're bad and by reinserting them you are making them have a better contact. This fixes 30% of problems. Next would be having a diagnostics run on the BCM. Checking for codes. This is helpful for pointing you in the right direction for electrical shorts. IE... Doors, lights ...This would need an electrical schematic to solve these problems. With the schematics you can also check wires for continuity. Which is important. If all wires check out, I would suspect the BCM is bad. This could also be checked with an Ohm meter. But you will need pinouts of the BCM. Pinouts tell you what wires go where and voltages supplies. If you are not familiar with an Ohm meter, I suggest that you find someone you can trust to diagnose the problem.

My 2003 Mercury Mountaineer has an electrical problem. It started about a year ago with the key fob not working, I have bought 3 and all won't work even after re-programing. now tonight I went to


Could be a windshile leak down the A-Pillar & water
gets into the delayed accy relay for the GEM Module
(Body Computer as ford called it for a few years) & you
get what you have now

Try Goolge as I did a few weeks ago for a relative
He had the same issue with the blower being on &
killing the battery

No real fix I found for the windshield leak
Seem a robot didn't put the rubber sealant
on correctly at the factory fo about 5 years
on several fords.

If it isn't water related then the GEM Module
controls all those body features

If you get a used one & match up the numbers,
you supposedly can avoid buying a reman gem
& the expense of having to reflash it to your factory
built combination

2003 BMW 325xi won't start, dashboard and radio go on.


My 2003 325xi died on the highway a few weeks ago, and I thought it was the battery. It turned out to be the alternator, which was an expensive problem to repair. If your battery is new, it could be the alternator, or a problem with the electrical system. I find the BMWs to be too complicated electrically, which often leads to problems! I'd check your alternator...

Electrical???


Since you've checked your voltage at the battery and alternator and they are ok, I would say it seems like an electrical issue. You need to put the truck on a diagnostic scanner to see what part (electrical part) is malfunctioninig.

Volvo S70 won't start - battery, generator, or other


usually multiple clicking (like a machine gun) does indicate lw battery voltage. did you get 11.9 volts with it running or car off? with running you should be over 13.6 min up to 14.0 volts. these cars have a fair amount of electronics with some residual voltage draws which may shorten battery life. 4 yrs is not too bad. i would consider replacing battery
