My Cruise Control doesn't work. The radio only plays to the 2 front dash speakers, no sound from all 4 door speakers. Time delay auto locks won't work. All 3 things stopped working at the same time?
JA: Have you checked the fuse? What size is your engine?
Customer: 5.3. Which fuse?
JA: What is the model/year of your GM?
Customer: 2008 GMC Serria
JA: Are you fixing your vehicle yourself? What have you tried so far?
Customer: Yes, have just started looking through the internet for similar situations. Don't quite understand how all 3 are related?
JA: Anything else you want the mechanic to know before I connect you?
Customer: It started about 2 weeks ago. Was very rainy. Then all 3 started working again. Then the next day they stopped working and haven't worked since.

I replaced the brake light switch. That took care of the cruise problem. Works now. I don't think the 3 are related. Coincidence that the radio and the cruise went at the same time. The lock delay does chime. I just couldn't hear it because it goes through the radio speakers. The radio worked again last night for a while but not today. It sounds like the very small dash speakers are working but nothing in the door speakers. I am thinking it is the radio itself. I will pull the radio out this weekend. Any thoughts or experience the radios going out on the GMC pickups??

I have seen plenty of radio failures and not just GM related. At my dealer I bet we replace 3-4 radios a week.

If there is anything you need form me, let me know.
