Hey there. Im new to this site and have seen lots of helpful info so far. Anyways, I bought a flooded 2010 Silverado with 24000 miles on it. It runs and drives, and did when I bought it. Water wasnt too high, but had to replace the wiring harness in the cab and also re-pin some corroded off wires that came off the dash wiring harness. Replaced the main block that the harnesses go into under the dash, replaced the seats and wire harnesses to the doors. Drained and services all the fluids. Now I cannot get the lights on the dash to come off. Check engine light, service 4 wheel drive, abs light, airbag light, Speedo doesnt work, temperature control blows hot on drivers side even when ac is on, but blows normal on passenger side. My buddy owns a shop and hooked up to his scan tool , he checked the lights and codes and couldnt get them to turn off. And for some reason his tool couldnt even read the vin of the truck. I have a good amount invested in this and am at a standstill now, I dont know what to do or where to start.
