Ok, heres my problem:

My doors will not lock from the door switch, to the key, to the alarm, and even with the pass side lock button. BUT...the unlock works fine.

Now, I took apart the door, and I am getting a negative lock signal when I hit the lock button, so the switch is working fine.

I looked for fuses, and checked here, to see if anyone had had this problem, and couldn't find anything!!

Are there separate fuses, or relays somewhere else in the turck besides above my knee, and under the hood??

I have a Viper 791xv, that I am 100% ok!

Any advice would be great!

Thanks,
Brett

 

Could it be a relay??
Brett

 

POWER LOCK BROWN/WHITE (TYPE B) @ PLUG BELOW FUSEBOX
POWER UNLOCK GREEN/YELLOW and BLUE/YELLOW (TYPE B) Use both @ PLUG BELOW FUSEBOX, See NOTE *1

look at those wires and tell me how the 791xv is wired. how long did ago this occur?
notice the unlock has two wires, grn/ylw is for unlock and blue/ylw is for unlock detection. take a pic of it. could be wiring the wrong way thatll affect the system.

 

I have the lock to the brn/whit, and the 2 unlocks are diode isolated. It has been on the truck for about 2 years now, without a problem. Went to the dealer...and they hadn't a clue what was wrong!!

Anybody have any ideas????

please...Im dieing here!! I took out the fuse block, and there isn't an "integration relay" as found on this website through a search. I guess I'll get a new fuse box, and see if that fixes it.

heres a test you can do to be sure that the fuse block is workin properly:

at the lock wire, see if youre gettin neg while turning the key of the drivers door to lock. btw, pressing the lock button will not work on these wires.

if youre gettin a negative but no actuator wanting to move, theres possible that ur integrated circuit is affected. btw, this is pretty rare that this occur.

 

Yeah...everyone Ive talked to has no idea!!

It meters 12v, but then ground as soon as I hit both the door switch, or using the door cylinder. I can hear the relay click slightly when I hit the lock button, but it's nothing like the unlock click.

So, the lock/unlock relay is built into the fuse box huh? I looked at it yesterday...and figured so, but wasn't 100% sure.

drivers drlk actuator wire: 12v (+)
Lock Motor blue/white driver kick blue 12 pin plug
Unlock Motor pink/green driver kick blue 12 pin plug

meter that for final possibility.

 

I have the same problem.However, I do not have an aftermarket alarm.All is factory. I checked the fuses.They are fine. Is there a door lock relay somewhere that I could change?

 

Stupid, but mine just "started working"...I called and talked to one of the greatest service guys ever, and he said its either of the 3:
1. a bad actuator (But only one door wouldn't work...)
2. I loose lock rod in the drivers door
3. A Broken/Cut wire in the drivers door jamb loom thing

I just got back from NC (TONS of sweet Runners in the OBX part, btw!!)

i had the same thing happen. pissed me off and all i did was squeeze the piece that goes through the door and into the dash (some type of tubing with wires behind it) and smoved it around. worked ever since. prob should get in there and see WTF but when it F's up again.
also i have the 791x
