I have done this repair once several years ago with great success. Now the problem has come back! Until I am able to contort myself to do it again would it be ok to "Hotwire" my radio so I don't have the constant interruption?

Do the 1993 cars have this bcm and the same issues?

 

If it is this same problem, it's also disabling your power windows, too. So you'd have to apply 2 hotwires.
Seems to me the repair is simpler than hotwiring.

I didn't have to contort myself to do it. (Too old to do so if I needed to). I just sat on my creeper on the garage floor next to the car.

 

Hmmmm that's an idea. When I did it I was in the car having to reach up under the dash after removing the glove box and of course had difficulty getting it un plugged from the harness. Not sure why its happening again now but whatever. Just seemed like its easier to sit in the drivers seat and pull the radio. Others have suggested that the factory theft system could be an issue so I suppose I'll just do it as soon as the heatwave we are having dies down.
Thanks for the idea!

 

no bcm. not sure what would cause same issue. bad ground, bad fuse connection, bad wire connection.

 

I got those symptoms with my new-to-me 1998 Z-28. Found out about the BCM, and a reflow (re-solder) of the pins fixed everything for me.

For anybody who has trouble with soldering, I work in electronics, and FLUX is the key to success. I can help. Do not use acid fluxes on electronics. Rosin fluxes are lame, but might work. Never leave flux on a finished job, it just causes problems. Wash/scrub any flux away, before you call the job Done. This is a great flux for anything from electrical to plumbing (non-acid, and safe for use on drinking water pipes). Wash away any of this flux with water, not chemicals, when done. Two ounces is all you need for many, many repair jobs.
