I have a paddle like switch right above my cd player and below the ac controls does anybody else with an 86 4Runner know what this was originally used for? My 4Runner was rewired really weird and it sometimes doesn`t start because something has drained all the battery power. I`m having trouble finding the electrical drain and since this switch makes my passenger side window go up and down regardless of whether my key is in the ignition or not I think it might be the drain. I think knowing it`s original purpose might help the mechanic to find the right wires faster.
