gauges and ac not working

[bigwhite4door901]

started up the tahoe after my battery had died and now my gauges and front ac aren't working. anyone have an idea of wat fuses I should check? already checked the obvious ones

that is it? nothing else? well you have two electrically separate issues. they have nothing in common with each other until they reach the battery wire to the under hood block. an if was the **** fuse or wiring in the under hood block they would knock out a whole lot more. you have anymore details?

I haven't had a chance to delve into it any further but I found some posts on an avalanche forum about the dash having to so with a ground so I'm going to look into that more and see it has me stumped for sure

it was the main ground strap to the block causing it to act crazy. now to just figure out why my ac compressor isn't firing

compressors should pump not fire

what do you see or not see happening?
