🚨 WHEN YOUR DASHBOARD GOES CRAZY… WHERE DO YOU EVEN START? 🤔🔧
We had a 2007 Chevy Avalanche come into the shop with a very unusual electrical problem. The customer reported no interior power, no power windows, and all of the dashboard gauges had randomly stopped working. To make matters worse… the vehicle wouldn’t even start! 😳
The ONLY thing inside the vehicle that still worked was the sunroof! 😂
Our first step was to connect our state-of-the-art diagnostic scanner and see what the vehicle was telling us. When we pulled the codes, we found nearly 50 diagnostic trouble codes! 🤯
With that many codes, it would be easy to start replacing parts and hoping for the best—but that’s not how proper diagnostics work.
One code in particular caught our attention: NO COMMUNICATION WITH THE AIR BAG MODULE.
We knew the air bag module was located under the seat, so we went straight there for a visual inspection. Sure enough, we found the module had been exposed to water, resulting in significant corrosion. 💧⚡
That one failed module was causing communication problems throughout the vehicle and creating a domino effect of electrical issues.
We replaced the air bag module, programmed it to the vehicle, cleared the codes, and performed a complete system check. Once everything was verified, the Avalanche was back up and running—and another happy customer hit the road! 🚙💨
