Anybody with a Tahoe 222?

[IBChillin']

Hey all. I have a Tahoe 222 that spent a few years uncovered in the Arizona sun and I need to know what the rocker switches controlled that were in each of the positions in this panel. I know the lower right was the ignition and the small hole was the horn. I can see that the blower switch was bottom middle but can not tell what the three switches on the left side originally operated. Any help would be appreciated!
