I’m having a problem with my 94 Z28, the clock on my radio remains on, drains my battery, checked the RCL button, not stuck.
I found tonight that if I pull the courtesy fuse the clock will go off. Could this be a BCM, RAP issue or just a bad factory radio?

 

No BCM in a 94. Was added in 1996.

Which radio…. Bose or standard? And the radio is “off” when the key is “off”? Only the clock stays illuminated?

I believe with the Bose system, the clock and memory are directly powered by non-switched power from the courtesy fuse. Looking at the schematic for the Bose, would not involve the RAP module. The RAP feeds power from Radio fuse 17.

I can give you a link to the 1994 factory service manual.

 

And let's move this to “General 1967-2002 F-Body Tech”. More likely to get help there than here on “New Member Intro”.

 

It’s a Delco radio, the radio stays off but clock will not shut off unless the courtesy fuse is pulled

 

Let me contact a friend who knows the Delco radios. I'll see if he has any ideas.

 

Is it a cassette or CD?

 

He came back December 3 at 7:53am to read your response, but I guess answering your question was too much bother.

Sorry to waste your time on this one. Another account to add to the "ignore" list. SMH

 

Sorry to be such a pain to you?? Didn’t get any notification about a response didn’t mean to ruin your day! If it will make you feel better, add me to your ignore list

 

So….. without “notification” you just happened to come back 33-minutes after he posted his response, you (hopefully) read his simple question….. but didn’t bother to post a simple 1-word response. You must be a verrrry busy person. Good luck.
