When you say the harness plug was unhooked behind the dash, do you mean the actual plug to the heater control or further down the harness?

I was having some instrument panel light problems that i couldnt figure out , the fuse was good but for some reason it still didnt work . changed fuse and it worked , i think it had some sort of build up on the terminals that blocked the current but it wasnt blown.
