I am not sure how to access the back of the switch.. Also what is the switch supposed to do in all positions?

I did pull the relay and measured for dv voltage at the wires with thr switch in each position but it's very tight in there and without knowing what wires go where it's tough to say for sure.. I believe there were 4 or 5 relays mounted together..
I pulled a couple and checked but I was unable to get my leads in a good position to check them all
What are the wire tags on each of the switch positions?

Thanks I'm hopefully I will be able to get this sorted out soon.. We did just get some snow so I Won't be driving it for a few days at least..
