I Need Help In Locating Power Door Lock Relays, And Are Fuses And The Relays The Same? No Power To The Rear Doorlocks And Now The Passenger Door Is Acting Up. Will Not Work With Remote Or Manual Door Switches

Go to www.fleet.ford.com and click on maintenance tab, then owners manuals and follow instructions.

Thank You So Much

No Luck On Finding What I Need On Fleet.ford I Already Have A Manual, I Just Need To Locate Those Relay To Test To See If They Are Ok Or If Have Bigger Problems.fleet.ford Would Be Great For Those With Out Manuals

I will try to send you a copy of the wiring diagram. The diagram does not show a relay for the locks. Check to see if current is going from the master switch to the others that are not working. If no current coming out, replace master switch.
