No fans w/ abs codes
Today I lost fans, hi and low speeds, ABS christmas tree came on, and "fan control 2" P0481 code popped up. I cleared the codes before realizing the fans weren't actually working, figured it was a weird fluke since I had just flashed it a few minutes ago, but they were working immediately after the flash.
I have power to the hi circuit of the relays, the fuses have power and aren't blown and I swapped them with known good ones just in case. I can jump it through the relay pin on the fuse box and get the fans to work. The "fan controller" relays are good as well and I swapped them with other known good relays just in case. My first guess would be a ground, but I can't find any bad ones. Any ideas? EDIT: Now the drivers window won't move more than an inch, and then it jumps up and down like it's trying to learn position or something, and then gives up and won't do anything until I key cycle.

On a side note, it also fixed my window problems, and the abs codes stopped coming back. I'm just going to call it gm wiring and be happy it's fixed.

Set the fan table at 100% at 160 degrees and be done with it.
