2nd generation Electrical Issues

[xaviervp]

I just purchased a 2000 explorer well taken care but of course has a few issues which some for me fall under TLC and maintenance like the squeeking
of the front end which having fords in my life since a kid im used to it but in process of fixing.

Question in hand I found a few fuses missing after purchasing the car and giving it a overall check and maintenance they are as follows.
all in the inside fuse panel next to drivers door.
#5 DLC
#27 DRL, Backup Lamps Switch, DTR Sensor, Electric Shift
#30 Park Lamp/Trailer Tow Relay
#31 Not Used
and
#35 Rear Blower Motor (w/EATC)


replaced all of them and 2 items not working are now working OD and backup lamps but i have an issue with one item.

Fuse #5 Data Link Connector

When i put this fuse in and i exit the vehicle if i beep the keyless remote
once everything is ok but if I beep it twice I get a horn confirmation and my
lights above the headlights turn on and STAY on indefinitly.

if I remove this fuse the keyless works fine beep it twice and car locks
and flashes the lights and horn once i have not been able to find anything else that is not working except for the typical intermitent radio display
which i might fix or replace with a better head unit.

What is the DLC?
What is it for and why if i click the remote twice my lights turn on istead of flashing should they not just flash as confirmation for the alarm / locks

By the way in case someone asks this is the factory keyless entry/security not an aftermarket.

If anyone in this forum if savy enough with the electrical on this vehicle
i will apprciate any help in resolving this dilema i have worked with cars for decades both the mechanical and electrical side but this has me stumped

Thank you
Xavier

DLC=Data Link Connector - comuniction link for the PCM,GEM,Remote Personality Module and OBDII sytem.
With the fuses in place, try removing the positive battery cable for 5 minutes to reset.
Sometimes this will fix odd problems.

my 2000 Mountaineer 5.0 also has no fuses in the #5 #6 #23 and #31 spot on the fuse panel
as far as i can tell the #6 is blank because I have auto climate control
the #23 and #31 are supposed to be empty per the owners manual
but #5 is empty My DLC does work, the truck had a code when I bought it, I repaired the sensor causing the CEL, and the light is now off.

I have been kicking over the idea of adding a fuse in that empty spot to see what would happen, but after reading your post I think I will leave it empty.

My DLC functions as it should as far as I can tell without the #5 fuse

i tried putting the fuse on again and as long as i dont beed the remote twice
when i lock the car everything is fine but if i beep it twice my daylight driving lights come on and stay on i tried it and after 1/2 hour they were still on till i removed the fuse or cycled the key on and off.

for not fuse stays off till i can figure out why.
