Does anyone have or know where I can find a diagram showing which relays are which in the relay box that is located in the very rear of the passenger side of my 2008 Expedition EL Limited? I can't find anything in the owner's manual or when searching online tonight. I believe there are 7 relays (5 larger, 2 smaller) in this small rectangular box. I'm having an issue with my rear blower motor and want to be able to troubleshoot the relays. Any help would be greatly appreciated!
