hello all, I was wondering if someone could shed some light on how to do the power door locks wiring for my truck. I tried this mornign and failed. Now my door locks dont work at all. Please help 2003 Xterra, alarm is a fm 2009 from asian wolf. Green is lock output (-) and Blue is unlock output (-). Thanks for all the help!!

To what wires did you connect the door locks. According to DEI you would just have to tag the yellow wire for lock at the SECU and the WHITE/ blue wire at the SECU which is located to to the right of the steering column. When you mention that your door locks dont work are you talking about the door switch?

You blew a fuse, bro. Check all your lower dash fuses and ALL your engine fuses. You tagged the wrong wire when attempting to attach the blue/green wires from the alarm to the nissan. You then grounded a 12 volt carrying wire and blew a fuse -- i would hope that you didn't also fry a transistor in the asian wolf. ------------- The search function is your friend.

Well i have checked the fused. Found 1 that was blown. Replaced it and still nothing. Not sure what it could be. I checked the fused on the drivers side and the ones in the engine bay. Is there another location?

disconnect the blue and green wires (off the alarm) to whichever nissan wires you connected them to. Their connection may continuously be grounding the 12 volts that the power locking system is sending to the doorlock motor/actuator. I couldn't find a copy of the xterra service manual online (for free) so I can't go through the electrical wiring diagram (EWD) .. otherwise it'd be fairly straightforward to see which fuses are connected to the keyless entry/doorlocking system. re-check your fuses if the problem persists, you may have overlooked one -- are you just visually inspecting them or actually testing them? ------------- The search function is your friend.

I have it disconnected. They havent been connected since the doors stopped working. I have tested each one 1 by 1. Im looking for the ewd right now. Thanks alot so far for the help

no problem -- if you can link me to the EWD, I can help you figure out what's going on . You can go to tradebit.com and purchase the service manual for $20, or you can go to nissan's tech website and pay $20 and get a 24hr pass that'll give you access to the EWD/repair manual. btw -- which wires specifically DID you have the GREEN/ blue wires connected to? ------------- The search function is your friend.

sorry to second post but i hit post to fast.. and i now notice there is no current through the GREEN / WHITE wire.. so i think i might have shorted it somewhere.

These are the color wires I have for my Xterra diagram (2003): | POWER LOCK | YELLOW (TYPE B) | @ SECU, See NOTE *2 | | | POWER UNLOCK | YELLOW/RED (TYPE B) (Requires Double Pulse) | @ SECU, See NOTE *2 |
If there was 12 volts in a GREEN / WHITE wire at the SECU and there is now NO voltage in that wire, it's the best news you can give yourself. It basically means you grounded that wire (with the negative -500mA) charge from the unlock wire of your alarm brain, and it blew the fuse that supplies the power to that green-white wire. Therefore, you are still missing a fuse. I really wish I could see that EWD b/c I could solve this for you in 5 minutes b/c I've been in this situation before. Places to look -- lower dashboard fuse box -- sometimes there is a passenger side fusebox... Better yet: https://www.courtesyparts.com/nissan-manual/pdf/2003-Nissan-Xterra.pdf page 8-7 (fuse box in the engine compartment) page 8-31 passenger fuse box Is there anything else electrical in the car that is NOT working? Frequently one fuse in the engine bay will control several things, i.e. dome light, parts of the SECU and keyless entry, etc. If you can find anything else that isn't working, you can push back in the circuitry (i.e. go closer to the battery) the location of a blown fuse. If it is Just isolated to the lock/unlock, then it's closer to the interior fuses. ------------- The search function is your friend.

Oh .. i see what you did -- you tied in the GREEN/ blue wires to the LOCK AND UNLOCK MOTOR WIRES (GREEN / WHITE )-- these wires are used in a 5-wire lock/unlock wiring scheme -- you weren't supposed to use these (obviously, right?) You have a type B locking system so you were supposed to use the yellow and yellow/red wires as above. Basically, I am reaffirming that there is a blown fuse somewhere ------------- The search function is your friend.

Well im at work right now but im having my wife go to autozone to get the diagram for free. Also see if she can use her charm and get one of the guys there to take a look at it.. lol

which fuse was blown (that you had stated you changed, earlier) by the way? (amperage? location (lower dash vs. engine bay)

it was a 15a in the engine bay. Im trying to remember the name of it but cant. It was like a power spare one.

ok my wife just went to autozone. They claim its a relay that went bad. Funny part is none of them could find where it went. I asked her to get the diagram and like normal she forgot. Im still trying to find one for free but i might just have to give in and buy one. She didnt get the damn diagram to troubleshoot.

It's either a fuse or a transistor in the SECU ... if you end up investing in the tradbit.com or nissantechinfo.com servicemanual .. lemme know and I'd be happy to trace it back for you. I don't think it's a relay if you're hearing the relay clicking when you press the lock/unlock button on the door (driver's and passenger's door). Also, if you hear a clicking sound when you use the factory keyfob, then it is also likely not a relay. You grounded a 12 volt wire, so a fuse has to be out somewhere, and/or a breach in the SECU. What relay were they going to sell her from autozone?? The power locking control relay is built into the secu/fusebox i believe. ------------- The search function is your friend.

ok i found the diagram. Here is the whole service manual https://www.evlempire.net/alarm/2003_xterra.rar Now its states that in the fuse box in the engine bay its fuse F. I have checked this 40A fuse and works fine. Then in the fuse box in the truck on the driver side it says fuse 28. I changed that one today and still nothing. Now i see that maybe either the circuit breaker ( which i cant find) or i fried something.

Well done on the diagram! (i'm referring to page 18/72 of the bt.pdf file).. 40A -- try replacing it 7.5A -- #28 -- you replaced it already... ...the circuit breaker --- it's identified as connector M12 ... however, the *.rar file is missing some elements of the manual (section PG -- power, circuit elements, etc) -- if you can locate that circuit breaker, that would be your best bet. Also, if you go through the algorithm of the Power Locks section of checking all the power terminals and verifying their voltages . you can help identify based on their (nissan's) algorithm where the break in power is. It'll take about 1 hour but it'll be worth it. Worst case scenario -- you fried the SECU -- it's $250.00 online (approx) -- The funny thing too, is the the (terminall 55) GREEN / WHITE wire that goes to the door lock actuator (front driver's door) is a grounding wire, and it usually has 0-12volts going through it (a relay in the SECU must switch it over to ground internally and this then locks/unlocks the doors). Lemme know if you can find that circuit breaker, and try going through that algorithm. ------------- The search function is your friend.

I'm in the process of looking through both EWD's now -- are your windows out? You can definitely hear the clicking of a relay when you press the LOCK and/or UNLOCK buttons on either driver's or passenger's door? w/ Nissan keyfob? also, when you're testing wires this weekend, test the GREEN / WHITE lock motor wire w/ a Voltmeter, both in rest state and when the lock/unlock button is pressed. See if it carries a voltage at anytime. PAGE 31/66 (of the 2004 Xterra manual --> section PG): You'll note the location of the circuit breaker and power window relay. Also, is there a change in the locking/unlocking situation with the car in the ignition (III) position? ------------- The search function is your friend.

windows do work and that is correct i can hear the Secu's relay when i hit the door switchs and the nissan keyfob

Ok so i tested everything out today. It looks like the actuators are gone. I tested the wires all the way up to the actuators and they are fine and working. Just nothing from the actuator. Im going to find 1 today and test it out.

wow! hard to believe that a fuse didn't blow before it blew all four actuators -- do you recall hearing any very strange noises during your install/testing of the doorlocks after hooking up the lock/unlock blue/green wires?

well... now that I think of it .. if you connected your blue/green wires to the actuator/lock motor wires.. you may have continuously grounded all of them until they burned out -- still find that pretty hard to believe, but it might be a possiblity.
