after having driver side temp actuator replaced, my driver side speaker, alarms for for low fuel, door open... work intermittently. think it might be a loose ground wire but I did not replace it and don't know where to look. Can anyone help with this please.

 

I am new to the forums and to the Silverado but this seems to be a common problem. Some fix it by replacing the speakers and others fix it by replacing the stereo since that actually creates the alarms.
