I've got these exact same codes off my 2001 Tahoe 4x4. The car goes into limp mode and 10 amp fuse is keeps blowing located on the drivers side fuse box. I recently fixed a leaky transmission pan 2 twice and now I get all 5 codes at once.
I replaced the ignition switch think it would fix it but the problem still exist. Also some of the gauges and gear selector isn't lit.
I'm not very knowledgable on electrical stuff but I'd hate to take a 15yrs car to the dealership is there's a fairly DIY fix.
Anyone else experience this or help is greatly appreciated.
