Typical Hummer Flooding / Electrical Issues
I have a 2010 Hummer H3 that had slow flooding issues. Apparently there was a bad seal with my windshield and I never took my Hummer on the highway so didn't really notice it. This has led to a host of electrical issues. I will start with the codes I am getting.

When I took the carpet out I saw that some of the wires had some calcification. I took out the TCCM and there was no water damage thankfully. I really just think I have a corroded ground wire. Another issue was that over the course of the last year my stereo would go out from time to time. Never had any electric codes. When I took out the stereo boom all of the codes popped. There was a lot of water on both driver and passenger side, but much worse on passenger side. I also checked the yaw sensor and that appeared to be perfectly dry. I have the Hummer wiring diagrams and have started to watch a ton of videos on YouTube. I am just hoping some of you have some good pointers for me to finding where the grounds might have started to corrode (if that is even the case).

If you have a sunroof. Sunroof with lack of maintenance = water damage. Finally, a fix for clogged sunroof drain tubes
