My 96 stratus power door lock only lock and unlocks the drivers door. what could the cause be?

My 2000 jeep started doing this and found it was the driver door wiring , it goes used a lot and the wiring goes bad , also stereo speakers on the same line started to go bad. I just removed the fuse to the power lock and all is ok. Just dont have power locks anymore unless you want to pay $$$ to fix it or you can fix it yourself. Mine started to unlock and re-lock, something you dont want......hope this helped a little.

The BCM - body control module is what controls the power lock's , disconnecting power can cause some functions to need resetting .
Have the BCM checked for DTC'S - diagnostic trouble code's , that would be my first step . Do you know what wiring diagrams are an how to read them ? Free wiring diagrams here

Battery Disconnect or Replacement Problems


Driver Door Unlock Operation
When any of the door lock switches are placed in the unlock position, a ground signal is applied to the BCM through the door unlock signal circuit. Upon receiveing this signal, the BCM grounds the control side of the driver door unlock relay through the driver door unlock relay control circuit. Since the other side of the driver door unlock relay winding is connected to battery voltage, the relay is energized. This causes the contacts to close and complete the path from the DRV LKS fuse through the battery voltage circuit. Voltage is then applied to the unlock side of the driver door lock actuator through the driver door lock actuator unlock control circuit. Since the other side of the the driver door lock actuator is connected to the normally closed contacts of the door lock relay to ground, the driver door unlocks.
The driver door unlock function can also be accomplished by the BCM supplying ground to the driver door unlock relay control circuit by either of the following:
• A keyless entry unlock transmission
• A lock out prevention function

DTC B3130 00: All Door Unlock Circuit
DTC B3135 00: All Door Lock Circuit

Circuit/System Description
When any of the door lock switches are placed in the lock position, a ground signal is applied to the BCM through the door lock signal circuit. Upon receiving this signal, the BCM grounds the control side of the door lock relay through the door lock relay control circuit. Since the other side of the door lock relay coil is connected to battery voltage, the relay is energized. This causes the contacts to close and complete the path from the battery voltage circuit. Voltage is then applied to the lock side of the door lock actuators through the door lock actuator lock circuits. Since the other side of the all the door lock actuators are connected to the normally closed contacts of their respective unlock relays to ground, the doors lock.

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.

I have answered this subject many times: it is a bad BCM or Body Control Module. The problem begins intermittently, but progresses during two to three years and finally inutilizes all door locks. As BCM repair and removal from the dash is a real pain, I resorted to disconnect the wiring to the BCM and paid a much lower price to a Car Alarm installer to put an inexpensive alarm that comes with its own remote. In that way I use the new remote to lock-unlock and the original one to set the original alarm-inmobilizer. Amclaussen.

thier really is no other option.. thier are plastic clips that hold the linkage together.. it's common for those to break.. so the panel has to come off.

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.

lock actuator is bad...

you might want to get a new key from dealer, just make sure you turn key all the way when you unlock. if this does it again, just start the vehicle for a quick fix.
