07 cobalt radio not turning on

if you connected it though your 12v constant, sounds like you blew the fuse... that fuse is in the main box under the hood...

the "security system" on the car is ran through the HU harness, so if the ecm is tampered with, the HU wont turn on, but that will also be the least of your problems at that point.... have you checked the voltage on your constant and ACC power?

nah i couldnt check the voltage it started getting dark. how do i get the ecm to allow me to turn the hu back on? this is literally the only thing i can think of. cause i checked the ecm fuse under the hood already

IIRC sit in the passenger seat then look on the left side of the center console near you're leg and you should find a panle that pops out the fuses should be right there!

like a second fuse box? cause i checked all the ones under the hood. found it weird there were no radio fuses...

mast-im running the stock hu. i put in the toggle switch. used the 12v constant red/white wire and ran it that way.
kramer-i didnt unhook any wires. just spliced the plastic coating over the wires and wrapped the line output converter and the remote wires that way. when i put in the lineout it worked fine. sub bumped and everything. the girl just wanted a toggle switch put in and now im having problems.

oh, sorry.

whatever you do... do not try to mess with the ecm yourself... you need to hook a obdII connector, and appropriate computer and software to change anything on it... like i said, most likely is a fuse, or a bad connection.... check the voltage on the constant and ACC when you get some light, and then update here

yea i remember when my friend was installing his radio he had the same issue, there is a panel on the passenger side that had fuses as well

alright i will thanks man. i hope i dont need to get the ecm regulated. the hu doesnt say locked or anything so im hoping that it is just a fuse.

in most HU's with built in security, if something in the computer gets screwed... it will pop up asking for a code, or say lock... so the fact that it has nothing, is actually a good sign... has to be something simple as a fuse or bad connection
