Funny enough I am looking in the roof area on a 97 model. I am diagnosing a parasitic draw situation. I will update in a few hours if its in there. Alldata has a diagram that by my interpretation points in the roof area LFT center.
The expedition door lock relay could be stuck causing the grinding noise. Check to insure that the lock relay is working properly.
Your 1998 F150 has 3 relays for your power door locks : an all unlock relay / a driver unlock relay / and an ALL LOCK RELAY I'm guessing that the ALL LOCK RELAY has failed I'm sorry but I haven't found the location of the power lock/unlock relays on your F150 yet ( does anyone know the location of the power door lock / unlock relays on a 1998 F150 ? )
You will need a Multimeter to run some test on the switch and the wiring.
What about it?
The 2006 Nissan door lock relay switch is located inside of the drivers side door. You will need to remove the door panel in order to access the door lock relay switch.
The 2001 Chevy S 10 Blazer power door lock relay switch is located inside of the drivers side door. You will need to remove the drivers side door panel in order to access the door lock relay switch.
wher is the door relay of toyota corolla 2001
It depends, some are in the door, some are in a fuse box.
There are 4 compnets to the power door lock circuit, the door lock lock/switch, wiring, relay and lock motors. Are the locks both locking and opening? If so probably a bad power door lock relay $30.00, either way I would say relay is the most probable and then wiring harness shorting next.
There is no 1995 ford Expedition!
On a 1998 Ford Explorer , fuse # 18 , 25 amp , is for the drivers unlock relay , all unlock relay , and all lock relay
Vin the relay panel ,
