Drove the car. In the rain if it matters. Suddenly all gauges dropped to zero I got service airbag service stabilitrak service power steering. Blinkers quit working. Door locks would lock and unlock on their own. A/C knob won’t turn on the A/C or do anything. I still have the radio and the wipers. I did notice weeks before that a bulb behind my gas gauge display was flickering and then went out leaving a dark spot. But an instrument cluster failure wouldn’t mess with the locks or the A/C controls right? I’m so sick over this.

You are getting water in a connector that is causing these issues.

The issue is going to be trying to find it. I would suggest starting with the major modules like the ECM and ABS module.

Also, let's check the codes because that will help us figure out the possible module that has water getting in it. The issue we are going to have is this could be an inline connector as well so I would start looking in areas that get wet when it rains and look for corrosion or green growth in the connectors.

Below is the detail on the ECM and ABS that should help. Let me know what codes are there and we can go from there. Thanks
