well, i have a 2000 Blazer LS 4WD. one day i started my car, and then i smelt burning plastic coming from behind my glove box. now my deck was still working so i was like ok, whatever. when i turned off the car, my deck stayed on (which was normal till i open the door). i opened the door and the deck was still on. long story short, there is always power going to my deck and i have to unplug it every time i turn off the blazer. has anyone encountered this? or know what it could be? please, if you could give me any kind of knowledge on this, i would greatly appreciate it. i took out the deck and just ride around with nothing cause its a pain to have ti disconnect every single time. thanks!

 

did you hook both the red and yellow up together??That would be my guess. sounds like you are getting constant power. Did you buy the harness or hardwire the HU in?

 

it was all harnessed. i have lots of experiance installing car audio, electronics. this just really baffeled me.

 

I would look into the RAP circuit. that would make sense that it stays on.

 

Another possibility, did you ever find what melted?

Did you check for power and correct functionality at the red and yellow wires?

if always acting the same, Then unplug and check for continuity betweenred and yellowusing an ohm meter

IF all else fails, add a switch which controls power to both the red and yellow wires, then OFF is OFF, LOL
