Stereo & Electronics - random radio shut off during driving.
06-10-2008, 05:07 AM
Well, my stereo that's been installed for 3 years now has decided (in the last few months) that it likes to randomly shutoff. when this happens the windows won't roll down. Usually it's when going over bumps so I checked for a loose hot/ground, ended up re-crimping the hot wire and it seemed to be fine for a week or two. Also, when the radio shutoff, you could bang on the side of the console/pillar and it would light up for a second again making me think a loose wire.
All this makes me think the radio or a loose wire BUT here's the catch:
Sometimes the radio will work fine, I turn off the car and it just shuts off instead of staying on for the 10 minutes of retained power. Also, when this happens, the power windows won't work. It's as if somebody opened the door and killed the retained accessory power.
Also, when driving and the radio cuts out, if I turn the car off and restart it, it usually comes back fine. All this makes me think that it's something in the ignition switch.
I'd appreciate any help!

The retained accessory power that runs the radio and windows is controlled by the BCM. Several members have found that the wire at the BCM gets loose and causes intermittent connection. Try wiggling the dark blue wire at the BCM and see if you can duplicate the problem.

What is the BCM?

The BCM is the Body Control Module. It is a black box about the size of a paperback book mounted to the heater duct under the dash behind the glovebox. It controls several body related functions including retained accessory power, power door locks, keyless entry, alarm, audible warnings (chimes), hatch release, etc.

My car does this as well. I was wiggling some of the wires and that is totally my problem. The only hang up is, how the hell do you un-clip the harnesses from the actual BCM??? I can't figure it out for the life of me. I think the reason mine is messed up is because I had an aftermarket alarm installed. It looks like the fucking noobs over at Circuit City just electrical taped wires that they tapped into. Nothing like doing it the right way.... I'll have to get in there tomorrow and get those harnesses un-clipped. Anyone know how?
the weird thing is, sometimes when I wiggle the wires it will shut the radio off, and sometimes it won't. I can have the car parked but running and not touch any wires and the radio will shut off. It seems like the wire is loose or grounding out somewhere. This is a real fucking headache.

My car is doing the same thing. This is definitely helpful!
PS - God bless the search function! :usa:

Check this out.
I tried to track down this same problem for two years and someone here finally figured out how to fix it. I did the re-solder like the thread suggested and the radio/windows haven't cut out in over 4 months.

whoops forgot to post follow-up. re-soldering fixed it. I had a very tiny crack in the solder joint.
