Troubleshooting door locks

[K.B.]

Can someone post a step by step tutorial on power door lock troubleshooting including the 4 relays in a row on the ds rear panel.My door locks have suddenly stopped working all 3 lock switches. 2000 explorer sport

This would be awesome. My Door locks work on the rear passenger doors but not the Drivers door or front passenger door. Have to reach in from rear and open drivers door or passengers door.

I dunno if it is realted, but my door looks recently stopped responding the the fob. I tried to reprogram the fobs and the truck won't enter the "program mode" (locks actuating after 8 cycles of on/off)

@Geo_08, your RAP module might be failing.

I left my lights on and completely killed my battery. Jumped it, and everything seems normal, except keyless, and the door keypad, does not work. The factory number, nor my number, works on the keypad. I tried to reprogram my remotes, using the "off to on" eight times, but it never cycles the locks so I never get to push a button to reprogram. Keyless eventually failed. I picked up another RAP module with identical part numbers from the junkyard. Swapped them, and everything is back to normal.

Huh I wonder if I could have knocked something loose when I was back there fishing out some tools the previous owner had buried back there. For me the first time I noticed it not working (don't always lock this up) was soon after I hooked up my bluedriver computer.

My key pad hadn't worked for a long time, I wonder if that was a precursor.

Could be. You could unplug it for a bit, and maybe hooking it back up will fix problems. Find out your part number, and dig on eBay or hit your local junkyard for a replacement. You'll have to consider if the cost of the part is worth it if it does not solve your problems.
