Can anyone help me with this issue?
Recently on a cool morning when I turned on my radio for the first time of the day the the radio powered on, however there was no sound to the speakers. After about 15 minutes the speakers began to work normally. The radio continued to operate normally until another cool morning when I turned the radio on for the first time of the day. I have no idea what could be causing this issue. Could it be a fuse or other electrical component that needs to be replaced? 2004 Chevy Blazer, 4 door, 4 wheel drive,
Thank you.

 

Got a soldering iron? Sounds (no pun intended) like the radio has a bad solder joint(s); when cool/cold the joint contracts, not making contact, then as the radio warms-ups the solder joint expands and makes contact again. Probably at the connector terminals on the radio. Easy fix to try....if you have a soldering iron and know how to solder or know someone. Be happy to do it, but you would have to ship radio to me. I do not charge anything, only cost to you would be shipping both ways. But you would be without a radio for two weeks or so. If interested, send me a PM and I will give you my address.

 

Lanny soldered my ABS module for me. An $80 value!

 

Thank you. What a great offer. I also have the issue with my EBCM. Periodically the ABS light and brake comes on. I had it replaced by an repair shop an it worked fine for 2 years or so. Just this past week I got a SES light for P0171, then within a couple of days all light are off. The truck has run great the entire time. Can any of this be related? I am considering my best course of action. I appreciate your wisdom and expertise.

 

The ABS module controls the ABS and Brake lites...not the EBCM. Did you have the ABS module replaced or the BCM replaced? The solder joints on the ABS module get cracked or whatever..which is the usual cause for the ABS & Brake lites to come on.

The P0171 code is Bank 1 lean. Could be couple of easy things....like the inlet air snorkel is loose/cracked after the MAF...or the clamp on the backside of the MAF is loose. Just check all the hose clamps on the inlet air hose.
If none of those, then going to have to do additional troubleshooting.

 

I would also check the electrical resistance with a volt meter on the stock speakers. See if they're not blown. I just replaced both of mine this year.
