On my 2004 dodge stratus the door lock switch on the drivers side does not unlock the doors. It will lock all of the doors and the windows but it just will not unlock. The passenger side still works for unlocking and locking.

check for broken wires between the body and pass. door. pull back the rubber boot. its a common problem on these cars

Nick:
I would not go and fix the relays: those are inside the BCM or "Body Control Module" located under the dashboard to the extreme left or driver's side. Believe me, it is a nightmare to remove from the car and very expensive to repair at specialist shops.
In my 2002 Stratus Sedan R/T Turbo (Mexico), the door locks started to ignore the door switches or the remote at about two years from new, but as it was an intermittent failure, I didn't go to the dealer to fix it under warranty. But after two more years and just out of warranty, the failure was more frequent. After six years of use, all the doors were ignoring the commands from either the door mounted switches or the remote.

The thing is, "modern" cars are designed with too much reliance on software and computerized modules to perform simple tasks previoulsly done with simple wiring and relays. This is the case with the door lock actuated by a BCM. In the older Spirit, LeBaron, Reliant etc. generation designs, you had three wires to the small motor actuating the door lock mechanism. But some "too-intelligent" so called automotive designers decided a "better idea": to multiplex the lock/unlock commands on only two wires, "saving" a few feet of copper wires, but requiring the use of a complex Module, that ends up being much more costlier, heavier and unreliable! (but in that way the too-intelligent software (ab)using designers were happy).

I solved my problem by disconnecting the door locks wiring to the BCM and paid a much lower price to a technician that installs cheap car alarms that have their own remote control. In that way i saved about $350 USD... you decide what to do! Best Luck, Amclaussen.

Check main wire on drivers door to drivers door lock.

The wires coming from your door through the hinge bend back and forth... they eventually break after let's say 11 years. :)

I had this same problem I changed the master switch in the driver door and it fixed the windows and it may be your power lock switch there to.

I have checked the ground wire in the drivers door ?????? what about B+ voltage to the switch ? These vehicles wires from the body to the door break inside the rubber boot . Looking at a wiring diagram (so U know what wire is what ) Test with test light ,voltmeter etc... Video's on youtube for testing electrical circuits . Plus these systems are controlled by a DDM - driver door module .

Enter vehicle info year , make , model and engine size . Under system click on body & accessories ,then under subsystem click on power door locks or windows . Just to give you an idea of what's involved . Watch this video , jeep ,dodge , chrysler same thing .
Dodge Grand Caravan No Power Window No Power Locks CAN Trouble

On most cars you can disarm the system by locking AND unlocking the drivers door with the key. Check your owners manual if you have one.

If they dont lock when you do it whit the controls on the drivers side,desassemble the door panels on each one,check for signal on the locking selenoids those may be the problem.

poss u have a bad power door acclulatiors do u hear the power door locks on the other side? or poss bad fuse check fuses frist

I called dodge local service dealer and ask the chief mech. He said the lock unlock switch had two resistors, Lock was 7200 ohms and the unlock had a 620 ohm both going to the PCU (computer) with an reduced 12 voltage supply to the CPU the CPU looks at the amount of reduced and will energize the lock or unlock Solenoid. added the resisters to each solenoid lock 7200 ohm and unlock 620 ohm on the ASTRA 600 alarm output to the CPU. works OK.
Thanks for your Interest in my problem.
