2002 grand caravan power side door switch stopped working

My 2002 grand caravan power side door switch stopped working this weekend. The door will still open via remote or overhead control, just not the actual switch. Does not work on either side. Has anyone had a similar problem and if so, what was the problem?

I have a 2009 Dodge Grand Caravan SXT. Both sliding doors will not work when the car is on, whether its pushing the key fob button or the buttons in the van. But when the car is off, your able to push the...


DESCRIPTION
Each power sliding door is equipped with a Power Sliding Door Control Module (1) (PSDM). The PSDM is mounted directly to the inboard side of the power sliding door drive assembly (2) with two retaining screws. The drive assembly is mounted to the body near the bottom of the sliding door in the track cavity with the use of five retaining nuts. The wire harness and chain link track and the power sliding door drive assembly are visible with the door open in the lower door sill area.
Software technology has enabled the PSDM to detect resistance to door travel. This allows the power sliding door to stop and reverse direction any time an obstruction is felt or any of the command switches are operated. Battery voltage is supplied to the power sliding door system through a 40 amp fuse, located in the Totally Integrated Power Module (TIPM) assembly. The power sliding door lockout switch located in the front overhead console prevents opening or actuation of the power sliding door system when activated. In the unlikely event that the power sliding door system develops a fault, the power sliding door can still be operated manually from the interior or exterior door handle similar to a standard manual sliding door.
NOTE: It may be possible to generate Sliding Door Diagnostic Trouble Codes during normal power sliding door operation. Refer to the appropriate power sliding door diagnostic information for a complete list of diagnostic routines.
OPERATION Battery voltage is supplied to the power sliding door system through a 40 amp fuse, located in the Totally Integrated Power Module (TIPM) assembly. With the push of a power sliding door open/close command switch (key fob, overhead console or B-pillar mounted) a signal is received by the Power Sliding Door Control Module (PSDM). The PSDM receives this signal via the Controller Area Network (CAN) Data Bus circuit. The PSDM then signals the power sliding door cinching latch to release the door to the unlatched and movable position. The power sliding door drive assembly motor then starts an open cycle.
The overhead power sliding door switch is mounted in the front overhead console of the vehicle. The switch has resistors in parallel of 1.76K ohms, 3.17K ohms and 15K ohms. When pressed, the switch will have a nominal resistance of 1.76K ohms for the right sliding door button, 3.76K ohms for the left sliding door button and when not pressed, the switch will have a nominal resistance of 15K ohms.
The status of the overhead power sliding door switches is continually monitored by the circuitry within the ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN). The instrument cluster receives input messages from the overhead power sliding door switches over a hardwired connection. Whenever the instrument cluster receives an input from the overhead power sliding door switches it sends a function command signal to the selected PSDM. This message from the cluster to the PSDM is delivered via the Controller Area Network (CAN) data bus.
The B-pillar switch is located on the lower B-pillar trim panel and allows the rear occupants to power open or close the sliding doors. The B-pillar switch is an R-Mux switch that has a resistance of 3.6K ohms and 16K ohms depending on switch position. When pressed the B-pillar switch will have a nominal resistance of 3.9K.
The B-pillar switches are hardwired to the Totally Integrated Power Module (TIPM). The PSDM receives the message for operation status via the Controller Area Network (CAN) data bus. If all the necessary conditions are met the PSDM will then perform the requested operation. The B-pillar switch lockout feature must be disabled and the sliding door must be unlocked in order for the B-pillar switch to function.
The FOBIK switch sends a signal to the Wireless Ignition Node (WIN). The PSDM receives the message from the WIN for operation status via the Controller Area Network (CAN) data bus. If all the necessary conditions are met the PSDM will then perform the requested operation. The vehicles theft alarm must be disabled and the sliding door must be unlocked in order for the FOBIK switch to function.
When one of the PSDMs receives a command signal it checks the following:
  1. PRNDL Status
  2. Vehicle Speed Status
  3. Ignition Status
  4. Vehicle Theft Alarm Armed/Disarmed Status
  5. Sliding Door Latch Status
  6. Sliding Door Full Open Status
  7. Ambient Temperature
  8. Door Lock Status
  9. Sliding Door B-Pillar Switch Lockout Status
  10. Sliding Door Window Up/Down Status
If the appropriate conditions exist the PSDM will send a command signal to the selected Rear Door Control Module (RDCM) so the sliding door can be latched/unlatched as needed. This command signal is sent via the CAN data bus. Once the PSDM senses the latch function it will power the motor on the power sliding door drive assembly to open/close the sliding door as requested by the overhead power sliding door switches.
During the door cycle, if the PSDM detects sufficient resistance to door travel, such as an obstruction in the door's path, it will immediately stop door movement and reverse door travel to the full open or closed position. The ability for the PSDM to detect resistance to door travel is accomplished by hall effect sensors detecting the door motor speed.
The PSDM has the ability to learn. Anytime a door is opened or closed using the power sliding door system the module learns from its cycle. If a replacement power sliding door component is installed or a door adjustment is made, the module must re-learn the effort required to open or close the door. A learn cycle can be performed with a complete cycle of the door, using any one of the command switches or with the use of a scan tool. (Refer to 08 - Electrical/Power Sliding Door - Standard Procedure) for detailed instructions.
The power sliding door system is designed with a number of system inhibitors. These inhibitors are necessary for safety and/or feasibility of the power sliding door system. The power sliding door system inhibitors are:
  1. The power sliding door must be in the full open or closed position in order for the power sliding door system to start a normal cycle. If the door is not in this position (based on the input from the switches integral to the cinching latch assembly) the PSDM will only perform a power open cycle.
  2. The transmission must be in park or neutral in order for the power sliding door system to start a cycle.
  3. The front overhead console lockout switch must be in the "UNLOCKED" position in order for the power sliding door systems B-pillar switches to function.
  4. If multiple obstacles are detected during the same power open or close cycle the power sliding door may go into full manual mode.
  5. If severe Diagnostic Trouble Codes (DTC) are stored in the PSDM the power sliding door may go into full manual mode.
  6. Due to the high pressure created in the passenger compartment with the blower motor on high, the power sliding door may not complete a power close cycle unless a window is cracked, allowing the pressure to escape. This situation will only be experienced on some vehicles, or vehicles with brand new side door weather seals installed.
The hard wired circuits for the power sliding door switches may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. However, conventional diagnostic methods will not prove conclusive in the diagnosis of the electronic controls and communication between other modules and devices that provide some features of the power sliding door system. The most reliable, efficient, and accurate means to diagnose the power sliding door switches or the electronic controls and communication related to the power sliding door system operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.

POWER SLIDING DOOR SYSTEM WARNINGS


WARNING: Always disconnect the negative battery cable before attempting any power sliding door system service.
WARNING: Extreme care must be taken to prevent objects from entering the doors path once the door reaches the cinch motor contact (approximately 1 inch before fully closed). Never place objects in the power sliding door when cinching closed. The obstacle detection function is inoperative during the cinch phase and damage to the vehicle, power sliding door system or components and/or personal injury may occur.
WARNING: Never attempt to enter or exit the vehicle while the power sliding door is in motion. You could damage the power sliding door system or components and/or cause personal injury.
WARNING: Never attempt to drive away with the power sliding door in motion. You could damage the power sliding door system or components and/or cause personal injury.

The battery in my 2010 Dodge grand caravan shorted out. We had to take it out and get another battery. Once the new battery was installed, the power sliding doors do not operate from the interior bu


Sounds like the power sliding door master switch on the overhead console is either in the off position, or something has gone wrong with the switch or the wiring. I'd check that switch and perhaps even actuate is a few times. It's the one to the far right.

2002 Grand Caravan. Overhead console lighted switches are not lighting. The Map lights that shine straight down works but none of the others back lights. Side door switch,rear gate switch, garage door...


The first thing that comes to mind is that the dash lights scroll dimmer is scrolled all the way in one direction which manually shuts off all the interior lights, even if a door is opened. At night turn on the parking lamps and then scroll the dash lights dimmer until the dash, radio face, overhead console, etc is brighter. Turn off the headlamp switch. Shut off the engine and exit the vehicle. Interior lights on? Hope this helps.

All of these functions are controlled by a central electronic module referred to as the BCM (body control module), you must have the dealer scan this module and run it through an active test to see what is wrong, it may be a defective BCM causing this, but that needs to be programmed and is not a plug and play part.

Dodge has released some updated software for the power sliding door modules to correct this condition so the fix, is to have these modules re-programmed with the new software.
