problems with 4x4 and door locks

[bassxlr8r]

if you have a 2door and the alarm is aftermarket, it uses a reverse polarity locking system. to properly integrate anything aftermarket, the door lock motor wires in the truck have to be cut, and two relays are added. if the power supply/fuse to the relays or one of the relays itself goes bad, or if all of the wires are not properly connected, you will have no lock or unlock regardless of the switch or remotes. the clicking you hear may actually be the added relays. pull your drivers kick and look for a lt. blue and a white wire coming from the door boot that are cut or spliced (this is the most common place to grab these, some use passenger side though). 4doors are positive trigger locks, so if this is the case none of this would apply as no wires should be cut during install. what brand/model alarm do you have, and was it professionally installed (and when if you know)?

so im having kinda the same problem.. for like 4 years now, when i got my hoe it had a factory alarm and the door lock button in the truck does nothing, but the remote locks and unlocks the truck,

so the insides never worked,
and the cig lighter doesn't work either (same circuit)
anyway so i took the alarm out and the switch still doesn't work,
and now i have a viper alarm installed and same thing the remote works the locks but the switch in the truck doesn't work...

and the factory remote key fob still locks and unlocks the truck

weird i never figured it out..

thanks!! i donty fully understand because im not electircally incline but i will give it a shot with the blue and white wires. i believe i didi see a blue wire that had tow of them coming out of one. will chekc that asap,

so i bought a multimeter to check current, i checked the wires to the actuator on the driver side and they do have continuity. also checked it to the switch and it works, now how could i check to see if the actuators work? is there a way to test these or troubleshoot somehow to see if they even work. would i have to replace both in order for the door locks to work..... this is so frustrating...

I FOUND THE PROBLEM!!!!!!!!
the door locks wont work because something is wrong with the alarm brain or i need to put a fuse between my alarm to my wires!!
figured it out by unplugging the lock and unlock wires out of the viper alarm brain. then my door locks worked!!!
my friend that installs alarms says we might have to put a relay or a fuse to those wires because something about the current not enabling the door locks to work. whatever it is atleasy now i know. i hope this helps someone!!!
