Question about 1988 Cadillac Sedan DeVille

1 Answer

Jam door locks

Both the driver & passenger front doors are closed and locked, but when you press the "unlock" button on the driver's side both doors will not open. I tried to get the door panels off but it's impossible with both doors closed shut, im thinking some kind of lever came loose on the inside but i can't get to it. Do you have any ideas on how to go about doing this & what may have caused this problem in the first place?

How about the passenger side - does it unlock with the key and switch there? Can you open the drivers door with a key? If both these are true, probably the unlock switch on the drivers door is faulty.

SOURCE: The driver side door lock locks but will not unlock!

it is the keyless entry module! that is the only thing in line with the drivers door lock. the rest of the locks are all connected to a door lock relay. so that only leaves a broken wire or module. go to the module( located in the trunk on the back of the back seat first module in the group of three) and test the tan wire in connector "c" position 18 while activating the lock either from remote or one of the switches and see if you get a positive pulse when doing so. if yes then you have a broken wire from that point to the door lock motor/actuator. if you don't have a positive pulse then the module is bad.

if you have any more question please ask. good luck

You most likely have a central locking system that will stay locked until you can unhook the battery. This is sounds like a similar problem I had with my 95 BMW.

LOCKING AND UNLOCKING
You can use the power door lock control or the remote control to lock and unlock your doors and tailgate.See Tailgate Lock.
Power Door Locks
The power door lock control is on the driver and front passenger door panels.

AUnlock.
BLock. Remote Control
You can use the remote control at any time your vehicle is not running.
Unlocking the Vehicle (Two-Stage Unlock)
Press the button to unlock the driver door. Press the button again within three seconds to unlock all doors.The direction indicators flash. The direction indicators flash twice to confirm the change. The unlocking mode applies to the remote control, keyless entry keypad and intelligent access.
Press and hold both the lock and unlock buttons on the remote control for four seconds to disable or enable two-stage unlocking. Disabling two-stage unlocking allows your entire vehicle to unlock with one press of the button.
Intelligent access at the driver door unlocks your entire vehicle when you disable two-stage unlocking.
Locking the Vehicle
Press the button to lock all doors.The direction indicators flash.
Press the button again within three seconds to confirm that all the doors are closed.The doors lock again, the horn sounds and the direction indicators flash if all the doors are closed.
Mislock
If any door is open, or if the hood is open on vehicles with an anti-theft alarm or remote start, the horn sounds twice and the direction indicators do not flash.
Activating Intelligent Access
General Information
You can unlock and lock the vehicle without taking the keys out of your pocket or purse when your intelligent access key is within 3 ft (1 m) of your vehicle. Intelligent access uses a sensor on the back of the door handle for unlocking and a separate sensor on the face of each door handle for locking.
The system does not function if:
  • Your vehicle battery has no charge.
  • The key battery has no charge.
  • The key frequencies are jammed.
Note: The system may not function if the key is close to metal objects or electronic devices, for example keys or a cell phone.
Note: If the system does not function, use the key blade to lock and unlock your vehicle. See Remote Control.
Unlocking Using Intelligent Access
With your intelligent access key within 3 ft (1 m) of your vehicle, touch the unlock sensor on the back of the door handle for a brief period and then pull on the door handle to unlock, being careful to not touch the lock sensor at the same time or pulling the door handle too quickly. The intelligent access system requires a brief delay to authenticate your intelligent access key fob.
Locking Using Intelligent Access
With your intelligent access key within 3 ft (1 m) of your vehicle, touch the outer door handle lock sensor for approximately one second to lock, being careful to not touch the unlock sensor on the back of the door handle at the same time. After locking, you can immediately pull on the door handle to confirm locking occurred without inadvertently unlocking.
Note: Do not use the outside door handle as a roof cargo strap.
At the Electronic Tailgate (If Equipped)
Press the exterior tailgate release button inside of the tailgate handle. The tailgate unlocks and opens. See Electronic Tailgate.
Smart Unlock
This feature helps to prevent you from locking your intelligent access key inside your vehicle's passenger compartment or rear cargo area.
If you leave your key in the ignition, when you open the driver door and lock your vehicle with the power door lock control, the doors lock then unlock.
You can still lock your vehicle with the key in the ignition by:
  • Using the manual lock on the inside of the door.
  • Locking the driver door with a key.
  • Using the keyless entry keypad.
  • Using the lock button on the remote control.
Smart Unlocks for Intelligent Access Keys
This feature helps to prevent you from locking your intelligent access key inside your vehicle's passenger compartment or rear cargo area.
When you lock your vehicle using the power door lock control (with the door open, vehicle in park and ignition off), your vehicle searches for an intelligent access key in the passenger compartment after you close the door. If your vehicle finds a key, all of the doors immediately unlock.
In order to override the smart unlock feature and intentionally lock the intelligent access key inside your vehicle, you can lock your vehicle after all doors are closed by using the keyless entry keypad, pressing the lock button on another intelligent access key or touching the locking area on the handle with another intelligent access key in your hand.
When you open one of the front doors and lock your vehicle using the power door lock control, all doors lock then unlock if the ignition is on.
Autolock
Autolock locks all the doors when:
  • All doors are closed.
  • The ignition is on.
  • You shift into any gear putting your vehicle in motion.
  • Your vehicle reaches a speed greater than 12 mph (20 km/h).
Autolock repeats when:
  • You open then close any door while the ignition is on and your vehicle speed is 9 mph (15 km/h) or lower.
  • Your vehicle reaches a speed greater than 12 mph (20 km/h).
Autounlock
Autounlock unlocks all the doors when:
  • The ignition is on, all the doors are closed, and your vehicle has been moving at a speed greater than 12 mph (20 km/h).
  • Your vehicle comes to a stop and you switch the ignition off or to the accessory position.
  • You open the driver door within 10 minutes of switching the ignition off or to accessory.
Note: The doors do not autounlock if you electronically lock your vehicle after you switch the ignition off and before you open the driver door.
Enabling or Disabling Autounlock
You can enable or disable the autounlock feature in the information display or an authorized dealer can do it for you. See General Information.
Illuminated Entry
The interior lamps and select exterior lamps illuminate when you unlock the doors with the remote entry system.
The illuminated entry system turns off the lights if:
  • The ignition is on.
  • You press the remote control lock button.
  • After 25 seconds of illumination.
The dome lamp does not turn on if the control is set to the off position.
The lights do not turn off if:
  • You switch them on with the dimmer control.
  • Any door is open.
Battery Saver
The battery saver turns off the interior lamps 30 minutes after you switch off the ignition if a door is open and the dome lamp switch is on. It turns off the interior lamps after 10 minutes if the dome lamp switch is off.
Accessory Mode Battery Saver for Intelligent Access Keys (If Equipped)
If you leave the ignition on after leaving your vehicle, it turns off 15 minutes after you close all of the doors.

Opening the drivers door doesnt automatically open the passangers door


Some vehicle locking systems allow a single button press to unlock the driver's side door and require a second button press to unlock the passenger side door. Likewise, use of the key to unlock the driver's side door does not automatically unlock the passenger side.

I hve a 2007 nissan altma and the front passenger door wont open. I replaced the locking assembly, and as soon as i closed the door it locked again. When I press the unlock button it moves but nothing...


sounds like the actuator in the door that locks and unlocks the door is jammed or too weak to move the lock assembly to fully lock/unlock positions. the linkage may be in a bind that can cause the same problem.

I have a 08 chevy avalanche the driver side front and rear door locks won't work when I use my keyless entry button or on the inside driver panel. Could it be a fuse? Passenger side works fine I try...


Do the power windows work ? DDM - driver door module fuse 15 amp - location is the instrument panel fuse box , plus LT DR circuit breaker 25 amp. Circuit breakers rarely go bad . The power locks are controlled by electronic's .The passenger side has another power supply ,that's why they still work .
Door Lock System Components
The power door lock system consists of the following components:
• The driver door switch (DDS)
• The passenger door switch (PDS)
• The body control module (BCM)
• The driver information center (DIC)
• The rear door lock/unlock relay (LBEC)
• The reversible door lock actuators in each of the doors and liftgate

The front power door lock switches are integral components of the driver door module (DDS) and passenger door module (PDS). The switches are 2 position normally open rocker switches. When placed in either the lock or unlock positions, the switches provide a direct input to the DDS or PDS. The DDS or PDS monitors these inputs and sends a LAN message indicating a change in the switch's respective position. Modules which activate the power door lock motors receive the LAN message and activate the motor in the appropriate direction to lock or unlock the vehicle's doors and liftgate. The rear door lock switch provides a lock and unlock signal to the body control module (BCM). The BCM upon receipt of a lock or unlock signal will control the rear door lock/unlock relay and also send a LAN message to the DDS and PDS to perform the appropriate function.
The modules which activate the power lock motors are:
• The DDS (driver door lock actuator)
• The PDS (passenger front door lock actuator)
• The BCM (both rear door lock actuators and cargo door/liftgate)
The DDS and PDS are directly connected to the respective door lock actuator through the door lock motor lock and unlock circuits. Once a door lock or unlock request has been received, the module will supply battery voltage to one side of the actuator and ground the other causing the doors to lock or unlock.
The rear passenger and endgate doors are controlled by the BCM through the rear door lock/unlock relay which is incorporated onto the printed circuit board in the LH BEC. The BCM controls the unlock relay by providing ground to energize the coil and controls the lock relay by providing battery voltage to energize the relay coil. The energized the relay and allows voltage to be applied to either the door lock motor lock or unlock circuits. Since the other side of the door lock actuator is connected to the normally closed contacts of the opposing relay to ground, the doors lock or unlock.

It's possible you have broken wire or wires inside the flex boot from the body of the vehicle to the driver's door . This happens a lot .
