New issues just popped up

[Dogluvr]

All at once the following happened: remote unlock/lock stopped working, automatic lock when driving stopped, radio does not turn off when door opens. Replace BCM? Where is it located? I know it's under the driver side dash somewhere. Thanks for any help! If it's not the BCM, then what else is it?

 

Remote has new batteries, all fuses are ok.

I had something similar happen on my 2007 sierra. The same things you described, plus the dome light would not shut off. I replaced the drivers side door latch assembly and all was good.

Both door latch assemblies have been replaced but I appreciate the input. I should also add that the alarm is not arming either. I was wrong before: the automatic lock feature still works.

 

1. No security light flash and turn solid when locked. No alarm.

2. No remote function at all.

3. No radio shut off when door opens.

This all started at the same time...

 

Anyone have any more ideas?

 

Thanks again.

Update: today the alarm armed 25% of the time. I got in and out of the truck a bunch of times running errands and the radio shutoff even worked once when opening the door. I can even hear the small solenoid click when I open the door that activates the accessory shut off and arming the alarm. It had a three second delay when I opened the door, it waited a few seconds then activated. The rest of the time it did not work. Still no response from the remote except the panic button works every time... Weird. Still no ideas from anyone?

Update again. Now the RAP feature is working again. I have no idea why it stopped and has now started again. Also the alarm is activating every time too. The only thing still not working is the key fob. Isn't there a relearn procedure? I've tried searching the site but didn't get anything to come up. Please advise.
