Power Windows Operation
The vehicle is equipped with power windows controlled by the door modules. Each passenger door power window can be operated, either from a switch built into the driver door switch assembly (DDSA), or from a switch mounted locally on its associated door. The driver door power window can only be operated from the driver door window switch built into the driver door switch assembly (DDSA).
When the driver door module (DDM) receives a window switch request from the DDSA, the DDM checks the Class 2 serial data to see if the status information is correct (i.e. ignition switch position) to permit window operation to occur. If the status information is correct, the DDM, either supplies power and ground to its associated window motor, or, if the request is for one of the passenger windows, sends a command via the power door serial data circuit to the passenger door module (PDM, LRDM, or RRDM) controlling the window. The passenger door module (PDM, LRDM, or RRDM) controlling the window then supplies power and ground to its associated window motor to move the window as requested.
When one of the local window switches mounted on one of the passenger doors is operated, the associated door module examines the request and checks to see if there are any messages from the DDM prohibiting the movement. If conditions are correct, and no prohibitive messages have been received from the DDM, the associated door module then supplies power and ground to its associated window motor to move the window as requested.
Do you know about computer controlled windows and door lock systems ?
Each door module has its own battery positive voltage supply circuit to use for power window operation, but they are all fed by the same 30 amp power window circuit breaker located in the rear fuse block. Each door module also has a seperate ground circuit to use for power window operation. These circuits are in the same dedicated connector as the window motor control circuits of each door module and are used exclusively for window motor operation.
Each door module also has a battery positive voltage circuit and a ground circuit that are used to power up the module ,as well as, to control mirror and door lock functions. Battery positive voltage to the DDM is supplied through the DRVMDL 10 amp fuse located in the rear fuse block. Battery positive voltage to the PDM is supplied by the PASS MDL 10 amp fuse located in the rear fuse block. Battery positive voltage to both the LRDM and RRDM is supplied by the RRDR MDL fuse located in the rear fuse block. Ground for the DDM is provided through a ground circuit to G200. Ground for the PDM is provided through a ground circuit to G201. Ground for the LRDM is provided through a ground circuit to G302. Ground for the RRDM is provided through a ground circuit to G301.
Each door module supplies battery positive voltage and ground, through the window motor control circuits, to its associated window motor. The window motors are reversible. The direction the window moves depends on which motor control circuit the battery positive voltage is applied to, and which motor control circuit the ground is applied to.To move the window in the Up direction, the module applies battery positive voltage to the window motor Up control circuit, and ground to the window motor Down control circuit. When a window movement in the opposite direction is needed, the module reverses the polarity and supplies power and ground to the opposite circuits to move the window in the reverse direction.
If the inspection reveals obvious concerns that can be readily serviced, correct the concern before continuing with Inspection and Verification.
If the concern remains after the inspection, connect the Rotunda New Generation Star (NGS) Tester, 007-00500 or equivalent, to the data link connector (DLC) located beneath the instrument panel to perform DATA LINK DIAGNOSTICS test. If the NGS responds with NO RESPONSE/NOT EQUIPPED for the driver door module, go to Pinpoint Test A . If the NGS responds with NO RESPONSE/NOT EQUIPPED for lighting control module, go to Pinpoint Test B . If the DATA LINK DIAGNOSTICS test is passed for the driver door module and lighting control module, retrieve continuous DTCs and execute self test diagnostics for the driver door module and lighting control module to retrieve current DTCs.
If self test is passed and no DTCs are retrieved, go to Symptom Chart to continue diagnosis.
If DTCs are retrieved for the driver door module, go to the Driver Door Module (DDM) Diagnostic Trouble Code (DTC) Index to continue diagnosis. If DTCs are retrieved for the lighting control module, go to the Lighting Control Module (LCM) Diagnostic Trouble Code (DTC) Index to continue diagnostics.
If the driver door module cannot be accessed by the NGS tester, go to Pinpoint Test A . If the lighting control module cannot be accessed by the NGS, go to Pinpoint Test B .
Rotunda Service Bay Diagnostic System (SBDS®) 001-00001 may also be used to diagnose this system.
You'll need more then wiring diagrams ! A good scan tool for starters .
The vehicle is equipped with power door locks. Each lock actuator is powered and controlled by the door module mounted in the individual door. The driver door module (DDM) is the master control for the door lock system but the rear integration module (RIM) contains the program that determines when the lock functions are permitted. ( RIM ) is rear integrated module , under the back seat . Also a fuse box is also located under the back seat.
The door lock operation modes are controlled by the rear integration module (RIM). The RIM examines the requested function from the DDM, or the remote function actuator (RFA), as well as the transmission shift selector position and the ignition switch position information available over the Class 2 serial data circuits. The RIM determines if a locking function is permitted, and commands the DDM to perform the function permitted. The DDM then sends commands to the rest of the door modules via the SBI to implement the selected locking function.
The vehicle is equipped with power windows controlled by the door modules. The DDM receives a window switch request, over the SBI serial data, from either the passenger door module wired to the window switch pressed or from the driver door switch assembly. The DDM checks the Class 2 serial data to see if the status information is correct (i.e. ignition switch position) to permit window operation.
Your best bet is take the vehicle to the dealer or a repair shop that knows how the system works . Are you familiar with GM class 2 serial data communication network ? You could inadvertently render your vehicle unable to start an run if the class 2 bus were to become shorted to ground .

start with the fuses replace it anyway or put a 12volt bulb in place of fuse , when its loading down it will shine bright , when normal it will not shine much at all.
be sure all connections to battery are working check for a second positive cable with a f useable link
Wow! Sounds like multiple problems but the back window popping open is probably the Body Control Module. Could be loosing ground at the body straps or positive from the battery cable connections during cranking?
Do this, With the door CLOSED !! push the 'down' button all the way and hold it for 10 secs, then up all the way and hold it for another 10 secs. Then repeat once. The window will return to normal after that.
The same circuit breaker feeds the driver door as well as the passengers doors . The wires inside the rubber boot from the body to the door are probably broke ,power or ground wire .Or the door module is bad . Are your familiar with electronic control modules ? The door functions ,windows , lock's , memory etc... are controlled by DDM - driver door module .
Door Control System Operation
This vehicle has five modules capable of performing door system control functions. Vehicle door system components (windows, locks, mirrors, etc.) are controlled directly by these modules. There is a door module located inside of each vehicle door:
• Driver Door Module
• Passenger Door Module
• LH Rear Door Module (LRDM)
• RH Rear Door Module (RRDM)
• LH Front Power Window Switch
Simple Bus Interface (SBI)
Each Door Module communicates with the other Door Modules on the SBI. The driver door module is the only Door Module that is capable of communicating over the Class 2 Data Line as well as the SBI.
Driver Door Module
The driver door module directly controls the LH Front door lock actuator, power window motor and the outside rear view mirror. The driver door module sends and receives messages received from the LH Front Power Window Switch to the passenger door module, LRDM and RRDM modules over the Simple Bus Interface (SBI) line. Also, the driver door module sends and receives message from other vehicle system modules via the Class 2 Data Line.
Pulling the door panel off an checking B+ voltage and ground for the module would be good for you to do , since you probably don't have a $6,000 factory Tech 2 scan tool to see if the DDM is communicating .
The driver door module has two main power feeds (high and low current), and two main grounds. The low power feed (battery 1) is used to provide power for the driver door module's logic and internal driver operation. The high power feed (battery 2) is used to provide power for systems that draw higher amounts of current (motors, lights, etc.). Operating current at the driver door module's battery should not exceed 3.0 amperes at battery 1, and 7.5 amperes (for 2 seconds) at battery 2 while the driver door module is awake, and 2.5 milliamps when the driver door module is asleep. For most driver door module functions, the driver door module will operate properly with a system voltage of 9.0-16.0 volts. If system voltages exceed 16.0 volts the driver door module will provide protection by disabling certain functions that may damage due to higher than normal system voltages.
What kind of manual do you have ? The info above is from a factory repair manual .
The fuse's ,circuit breaker for the door module are located in the rear fuse box , not under hood . PWR WDO circuit breaker 30 amp. , DRVMDL fuse 10 amp. The rear fuse box is located under the back seat . Watch this video ,different type vehicle but probably the same problem . Dodge Grand Caravan No Power Window No Power Locks CAN Trouble
Instrument cluster problem maybe . Without testing we'd only be guessing . Have seen this a lot at the dealer . The best thing would be to hook up a factory scan tool an check for DTC'S - diagnostic trouble codes first. The electronic's on these vehicles are complex to say the least . All the warning light's , gauge's etc.... are controlled by a module an data network . GM class 2 serial data buss. Power windows also are controlled by a module . DDM - driver door module.
