I have a 2007 gmc sierra classic crew cab. I started having problems with my radio this week so I decided to change out the head unit. Put a new one that is recommended for my truck and same thing is happening. First thing in the morning the radio only comes out of the small speakers in the front doors and sounds horrible. This lasts till about the same time every day around 11am. Any ideas of what can be causing this?
No amp. What has me stumped is that it worked fine last night and now it is doing the same thing the old stock radio was doing. Would putting it on a code reader maybe tell me something? My check engine light has been on for about 6 months now. Last time I did that they told me it said a part my truck supposedly doesn't have was showing defective.
The radio did not start working yesterday at all. In doing some research the only thing I have come up with is possibly the bcm. Is there any way to test this?
have the same problem?
