Where are the fuses for the power dock locks on a 2006 montecarlo06ss


DR/LCK fuse 25 amp . located in the I/P block
Fuse Block - I/P
In the right front kick panel

Power Door Locks System Components
The power lock system consists of the following components:
• Body control module (BCM)
• Driver door lock cylinder switch
• Front passenger door lock cylinder switch
• Driver door lock switch
• Front passenger door lock switch
• Door lock actuators in each of the doors
• DR LK Fuse 20-amp
Door Lock System Controls
The Power Door Lock System is controlled by the body control module (BCM) and can be activated by any one of the following:
• A door lock switch lock or unlock actuation
• A door lock cylinder switch unlock actuation
• A keyless entry transmitter actuation
• An automatic door lock actuation (Personalization function)
• An automatic door unlock actuation (Personalization function)
Door Lock Operation
When the body control module (BCM) detects a transition of either of the door lock switches to the lock position, it switches the door lock actuator lock control circuit to voltage. Since the lock actuator unlock control circuits are at ground potential within the BCM, the door lock actuator motors transition to the lock position.
Driver Door Unlock Operation
When the body control module (BCM) detects a transition of either of the door lock switches to the unlock position, it switches the driver door lock actuator unlock control circuit to voltage. Since the door lock actuator lock control circuit is at ground potential within the BCM, the left front (LF) door lock actuator motor transitions to the Unlock position.
The driver door lock actuator unlock control circuit is a dedicated control circuit used only for the driver door lock actuator motor. This is done so that the driver door may be unlocked by itself using a keyless entry transmitter or an automatic door unlock function (if programmed).
Passenger Door Unlock Operation
When the body control module (BCM) detects a transition of either of the door lock switches to the unlock position, it switches the door lock actuator unlock control circuits to voltage. Since the door lock actuator lock control circuit is at ground potential within the BCM, the passenger door lock actuator motors transition to the unlock position.
The door lock actuator unlock control circuits are dedicated control circuits used only for the passenger door lock actuator motors. This is done so that the driver door may be unlocked separate from the passenger doors using a keyless entry transmitter or an automatic door unlock function (if programmed).

2006 GMC Envoy: I tested all of the fuses and all of them check out but my power locks, cabin lighting, dash panel lights, etc. aren't working.


Which fuse box ? Do you know what a DDM -is ? Driver door module . Do you have any idea what all is involved in making these thing's you have listed work ? A lot more then a fuse , there could be DTC'S - diagnostic trouble codes stored in the principal Control module ,the BCM , That could save a tech. valubale time in diagnoising this problem !
Door Lock System Components
The power door lock system consists of the following components:
• Driver Door Module (DDM)
• Passenger Door Module (PDM)
• Liftgate Module (LGM)
• Door lock relay
• Door unlock relay
• Body Control Module (BCM)
• Reversible door lock actuators in each of the doors
• LR/RR LOCKS 10A fuse (relay supply voltage)
• Door lock switches in driver and passenger doors (switches are integral components to the DDM and PDM)
Did you know there is a fuse box in the rear of the vehicle ?
Fuse Block - Rear
Beneath the left rear seat
The inside lights are also controlled by the BCM , and the fuse's are also located in the rear fuse box .
The body control module (BCM) directly sends a 5-volt reference voltage to the instrument panel (I/P) dimmer switch which is then adjusted based on the I/P dimmer switch position and returned as a low reference and a signal to the BCM. The BCM uses this signal to directly control the desired level of instrument panel illumination lamp intensity.
DTC Descriptor
This diagnostic procedure supports the following DTC:
DTC B2620 Display Dimming Pulse Width Modulation (PWM) Input Circuit. There are several DTC'S that can set !
DTC B3801 Passenger Compartment Lamp Request Circuit
DTC B2610 Passenger Compartment Dimming 1 Circuit plus others for power locks .

Passanger side doors wont lock


From where , any switch ? driver door switch or either passenger door switch . This is a very complex system controlled by modules (microprocessors)
?€¢
The driver door switch assembly (DDSA)


?€¢
The driver door module (DDM)


?€¢
The passenger door module (PDM)


?€¢
The rear door module (RDM)


?€¢
The LH front power door lock switch


?€¢
The RH front power door lock switch


?€¢
The LH front door lock actuator


?€¢
The RH front door lock actuator


?€¢
The LH rear door lock actuator


?€¢
The RH rear door lock actuator


?€¢
The remote control door lock receiver (RCDLR)


?€¢
The power door serial data circuit


?€¢
The class 2 serial data circuit


?€¢
The DRVMDL Fuse - 10 amp


?€¢
The PDM Fuse - 10 amp


?€¢
The RRINMDL Fuse - 10 a
Class 2 and Power Door Serial Data Links
The class 2 and power door data circuits are both serial data links. The serial data circuits replace cables in the vehicle by multiplexing (time-sharing) data to and from each device over a single wire referenced to ground. If the power door serial data is lost, both the rear door module (RDM) and the passenger door module (PDM) enters the sleep mode. With the RDM and the PDM in sleep mode, no power door operations are possible.
Your best bet is to take it to the dealer or an ASE certified repair shop .

Passenger door locks don't unlock.


You need to understand how they work , do you know about automotive electronic controls ? Your switches are just inputs to the BCM - body control module !
Door Locks Power and Ground
For door lock operation, the IP Fuse Block supplies battery positive voltage, through the 15 amp DR LK/TRUNK fuse, to the BCM. The BCM uses this circuit exclusively to apply power to the door lock actuators. The BCM is also supplied a ground circuit, which it uses exclusively to ground the door lock actuators. When a door lock is pulsed, the BCM internally connects these two circuits to the appropriate lock and unlock control circuits to actuate the locking or unlocking functions.
When diagnosing door lock malfunctions, these circuits must not be confused with the other battery voltage and ground circuits of the BCM. The appropriate wiring schematic must be used to locate the correct circuits. Failure to identify the correct battery voltage and ground circuits of the BCM during diagnosis of door lock concerns may result in misdiagnosis and unneccessary parts replacement.
Passenger Door Unlock Operation
When the BCM detects a transition of either of the door lock switches to the Unlock position, it switches the door lock actuator unlock control circuits to voltage. Since the door lock actuator lock control circuit is at ground potential within the BCM, the passenger door lock actuators transition to the Unlock position.
The door lock actuator unlock control circuits are dedicated control circuits used only for the passenger door lock actuators. This is done so that the driver door may be unlocked individually before unlocking the passenger doors using a keyless entry transmitter or an automatic door unlock function, if programmed. When the keyless entry transmitter is used to unlock the passenger doors, the BCM requires a repeated unlock command before it performs the unlock function. However, when the unlock input is from a door lock switch, a single unlock command is all that is required to unlock all doors.

Door locks unlocks


Sounds like the main wiring loom into the door has been damaged.
Check near the hinges, where the door swings, to see if any damaged wires. Does the door lock and unlock from the drivers side switch?

if the fuse is good, check the switch that controls the side to side adjustment, these go bad pretty often for some reason,, try flipping it back and forth a few times, and try it,, if that doesn't get it,, your going to have to remove that switching control,, test it for continuity when the passenger side is connected, if it has none, replace the switch

Just bought a used 2007 pacifica. The remote key wont lock or unlock all the passenger doors. It works on the drivers door and the rear hatch. Is there any way this is a fuse or relay problem?


The passenger door locks are controlled through the passenger door module. Power to the module is supplied by 20 amp fuse #46 in the IPM (integrated power module) under the hood. Make sure the fuse is not blown.

Passenger window won't work its elelectric, acts like no power to it. Is there a fuse I have no book and can only find the master fuse box under hood?


Hi their is only one fuse for the windows and thats the one you have checked, if the other windows are working then the fuse will be ok.

if the drivers door has a seperate control for the passenger door try this and if it wont work from either the passenger side or the drivers side then the problem is going to be either the motor or the regulater and these are both inside the passenger door.

if how ever the drivers and passenger controls are seperate and you cant control the passenger side for the drivers door controls then what you can try is swapping the switches over from the drivers door to the passengers door, if the controls are the same then all you need to do is get a flat bladed screwdriver and pry the control up as its only pushed into place then unclip the wires and swap the switches over then if the passenger side then works you know you need to get a new switch of it still dont work then it will be either the motor or regulater at fault.

either way the door panel will need removing and you will need to test if you have any power going to the motor.

let me know if you need further assistance ok

plz rate this solution as i have a whole page of unrated posts, thanks
