2007 random electrical issues

[westrem]

I have a 2007 new body style Silverado 5.3.  I was driving home one night a few weeks ago and all the sudden my hazards came on, radio shut down and showed a phone icon, dome lights came on.  I couldn't turn the hazards off or the radio back on during this state.  I restart the truck and all back to normal and thought it may just be a fluke.

2 days later it happens again but the hazards dont come on this time.

A few days later the gauges all lose power, radio goes out, no turn signals or taillights or brake lights.  

During this same time my service air bag light has came on and has not gone away.

It always drives fine while these issues happen and after about 30 seconds it will come back alive and sometimes shut back off instantly for another 30 sec or so and then work fine for the remainder of my drive.  

I do have a windshield leak that would cause water to get my drivers side floor wet.  The foam was over the air bag module box under the seat so I ripped it off and my module is very corroded.  I have unplugged the module and looked at the connectors which looked good.  Could this module cause all these issues?  Should I drive with it unhooked to see if the issues with the electrical stuff goes away?  Is there something else I should be looking at?

That module is probably bringing the whole communication system down via a dead short, or a partial connection. I would check the body control module as well, under the center console. That is the unit that controls all the items that were flaking out on you.

 

I don't have a wiring diagram, but I'd bet your losing communication to the BCM. A good scan tool will probably show some "B" codes to back that theory up.

Usually when your airbag module gets corroded the truck doesn’t start.
You need to replace that module. That runs on the network for the ignition, cluster, infotainment, etc.

there was a recall for that problem, dont know if it will cover your truck but worth the research the recall number was N090270

That's a Canada recall deal.  I'm in USA Missouri.  I see this recall which is similar but only shows them to remove the padding over the module and nothing about replacing it like the Canadian one does.

09184A: Customer Satisfaction - Material Over Sensing and Diagnostic Module Retaining Moisture - (Oct 26, 2009)


Subject: 09184A -- Material Over Sensing and Diagnostic Module Retaining Moisture


Models: 2007-2009 Chevrolet Silverado

2007-2009 GMC Sierra

Currently or Previously Registered in Connecticut, Delaware, District of Columbia, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, , West Virginia, Wisconsin




--------------------------------------------------------------------------------

This bulletin has been revised to include an inspection procedure and a new labor code. Vehicles with vinyl flooring and no cutout flap require no repair. All technicians are to review the new inspection procedure immediately. Please discard all copies of bulletin 09184, issued October 2009.


--------------------------------------------------------------------------------

Condition
Certain 2007-2009 model year Chevrolet Silverado and GMC Sierra vehicles currently or previously registered in Connecticut, Delaware, District of Columbia, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia, and Wisconsin may have a condition where an electronic component located beneath the driver's seat may corrode due to a significant quantity of snow and/or water containing road salt or other contaminants entering the vehicle and saturating the acoustical padding beneath the carpet. The vehicle's electronic sensing and diagnostic module (SDM) is located underneath this acoustical padding. If sufficient moisture collects and is retained in the padding, it may cause excessive corrosion under the module; compromising the module seal and allowing water intrusion and system malfunction. This may result in illumination of the Airbag Readiness light, along with a "Service Airbag" message on the Driver Information Center, and in rare cases, deployment of the seat belt pretensioner and/or airbags.

Correction
Dealers are to remove the acoustical pad above the SDM.
