Where is the door lock relay located on a 1999 ford explorer? Electric door locks blows fuses. After replacing a fuse, the door locks will only work for a short time then blows fuse. I know the fuse/relay box is under the hood but I do not know where the relay is that goes to the door locks.

There are several relays that are controlled by this fuse. battery saver relay, trans shift relay, power window relay and more

Check the wiring to the rear hatch. The cables break and cause a variety fo problems like yours. You will have to take the plastic cover off and expose the cables.

Are the switches located near each other? Plug may have come off or on some models with console switches things get spilled in them???

relay may be under the hood.or behind glovebox.

it is either the drivers side door lock or the passenger side but i would go for the drivers door first, it wants a new lock but more often than not removing the door panel and squirting with a proper oil can with engine oil in around the door lock and the operating mechanism will cure it

Maybe you problem is with the switch, or check if power seat circuit has the regular fuse or rather one of those thermal ones.
Passenger compartment fuse panel
The fuse panel is located on the left hand side of the instrument panel facing the drivers side door.

Found this answer in anotherr forum and works for me. Power Door Lock Relay Location

Aux Relay Box #4 is in the rear driver's side removable panel with the tire jack.

This Relay box holds the Door Lock / Unlock relays (ice cube type). It also holds the Driver Door Unlock Relay and the ACC Lights Relay (rectangular relays).

Aside from the fuses, your drive side power door lock may be failing to work because of a bad door-lock relay system, or, alternatively, the locking switch/button, itself, is not malfunctioning and in need of replacement.

A great handyman site that specifies the above probable causes and more is the following link:

Good luck!

Hi, Yikes! Sounds like a control module problem as the things in common don't work independently. For example the driver combo lock works which activates the electric lock, this checks the fuses and relays in that circuit which would mean the switch on that door uses the same circuitry. The keyfob also goes through the control module but then again so does the rear lock but the module is the only real thing in common. The wiring harnesses are not in common either. The only thing I can think to do is have the module diagnosed on the computer. Sorry, But I hope this helps!
