Question about 2003 GMC Envoy

1 Answer

Main control module on driver's side does not operate the driver side window or the other windows. Also, sometimes the driver's seat heats up. *** It was raining one day and I went to let up the windows and the switch seemed to short circuit and would not operate the windows from the main module. The three other windows work but have to be operated individually at their respective door. *** What is the problem? Does the entire module needs to be replaced?

Seat heater comes on by itself in 2004 yukon denali


Heated Seat Components
The heated seat system consists of the following components:
• Driver and passenger heated seat switches
• Driver and passenger seat back heater elements
• Driver and passenger seat cushion heater elements
• Driver and passenger seat back temperature sensors
• Driver seat module
• Driver door module
• Passenger door module
When there are modules involved in the operation of any componet that's acting up , the module's electronic's could be the culprit ! But without testing who's to say what the problem could be !
I would have it check for DTC'S
DTC B2425 or B2430
The driver and passenger seat heaters are controlled by the driver seat module. Power is supplied to the driver seat cushion and back heater elements through individual voltage supply circuits. Power is supplied to the passenger seat cushion and back heater elements through a common voltage supply circuit. All of the driver and passenger seat heater elements are grounded by the driver seat module through individual low side drive control circuits. The heater element control circuits are pulse width modulated to ground by the driver seat module in order to control the seat temperatures by regulating the current flow through the heater elements.
DTC B2435 or B2440
The driver seat module relies on inputs from thermistors installed in the driver and passenger seat backs to control heated seat temperatures. The thermistors are 2-wire sensors supplied with a 5-volt referenced signal circuit and low reference circuit from the driver seat module. Resistance through the thermistors varies with temperature causing the heated seat sensor signal circuit voltage levels to decrease as the seat back temperatures rise.
Install a scan tool.
Start the engine.
Turn the heated seat ON.
With a scan tool, observe the Heated Seat Sensor parameter in the data list for the driver seat module.
Does the scan tool indicate that the heated seat sensor parameter is within the specified range?
0.078-4.94 V

Heated & cooled seats staying on while car is off and keys are out. The radio also stays on, I noticed the driverside window controls are not working either. The nav maps also read an error


This sounds like a computer glitch. Cars are becoming more computerised and as well as Engine Control Modules, there are body controller computers as well.

This might fix it, and is probably worth a try. Disconnect your battery for a couple of hours. This should reset all the computers. If that doesn't work, you need a dealership who have the software to interrogate the vehicle electrics.

My power seats and only the power windows on right side quit working on my 2007 silverado classic lt1500 I replaced the circuit breakers already and it did not fix the problem


Does you truck have Memory Seats ? There are 2 options of power seat systems available in full size trucks. The first is 6 way driver and passenger power seats without memory. The second is an 8-way driver seat plus 4-way lumbar with memory, heat and optional cool function.
If you replaced the circuit breaker , did you check for B+ voltage at the switch ? If you have memory seats there is a control module that is in the mix.
For the power windows same thing here ,the BCM - body control module is involved .A factory Tech 2 scan tool is still the best tool to use ,checking data parameters .
The switch for the front passenger power window has 2 positions UP and DOWN, and it's position is a direct input into the PDS. Upon receiving a request for power window operation (switch activation), the PDS supplies voltage to the power window motor right front up or down circuit and grounds the opposite and the power window motor runs to drive the window UP or DOWN.
The front passenger power window can also be operated from the driver master control. The front passenger window switch on the driver master control has 2 positions UP and DOWN and it's position is a direct input into the DDS. Upon receiving a request for front passenger power window operation, the DDS transmits a GMLAN message indicating the changed switch position. When the PDS receives this message, the PDS supplies voltage to the power window motor right front up or down circuit and grounds the opposite and the power window motor runs to move the window UP or DOWN.
GMLAN - is a data bus communication network that vehicle modules talk together on.
Rear Passenger Power Window Operation (RPO A31/AN3/DL3)
The body control module (BCM) monitors the window UP/DOWN command from the DDS. When the rear window UP or DOWN command is received, the BCM sends a signal to the appropriate rear window switch. The rear window switches continuously monitor the up and down signal circuits, if no function is being commanded, the signal voltage is at approximately B+ voltage. If the UP or DOWN function is commanded, the BCM signal voltage drops approximately 5 volts and the appropriate rear window switch will then command the window in the UP or DOWN direction.
Your best bet would be to take your truck to a GM dealer !

2004 Envoy XUV heated seats do not work on both sides. I press the button and the lights come on, when i release the button the lights go out. I checked the fuses mentioned in the articles on this site but...


If other functions such as window controls and power seat controls are normal, here are some possibilities;
1) Circuit Breaker #8 in rear fuse panel
2) Defective Driver Memory Seat Module (under driver's seat)
3) Break in data lines between Driver's Memory Seat Module and Drivers Door Module
4) Fuse 23 & 6 in rear fuse panel

Front seat is not moving


The d.c.m module( your seat switch) controls the window operation and seat operation. It also relays signals to other control modules on the data system. does any other components not work? You can unplug certain connecter but not the main can connecter to the data bus. For the hell of it check the fuses. I beleive your schematic is located in the left side of the dash(behind plastic cover) visible when door is open. If not refer to owner's manual where the fuse schemstic is. good luck

1999 cadillac seville sts driver side master control pannel dead


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 .

no, different.

Principles of Operation
Note: Upon installation of a new driver door module (DDM), the module must be reconfigured. Refer to Section 418-01 . The DDM is connected on the standard corporate protocol (SCP) communication network. The DDM controls many functions including power windows, power door locks and remote keyless entry. The DDM also communicates with the driver seat module (DSM) to control the power mirror and seat memory functions.
--------------------------------------------------
Principles of Operation
The driver seat module (DSM) is connected on the standard corporate protocol (SCP) communication network. The DSM controls the driver power seat and communicates with the driver door module (DDM) to control the driver seat memory and both outside memory mirror functions.
---------------------------------------------------
Principles of Operation
The lighting control module (LCM) is a microprocessor based module that controls several vehicle subsystems. The LCM responds to electrical input signals from various switches, sensors, and external modules. The LCM is located under the LH side of the instrument panel. Subsystem functions of the LCM include headlamps with autolamps, turn signal lamps/hazard flasher lamps, cornering lamps, parking lamps, daytime running lamps (DRL), courtesy lamps, demand lamps, battery saver and control backlighting. The LCM interfaces with the driver door module (DDM) through the standard corporate protocol (SCP) communication network for the illuminated entry feature.
----------------------------------------------------
Principles of Operation
The air suspension module is linked to its own data link connector (DLC). The air suspension module controls the air suspension and the variable assist power steering VAPS. For additional air suspension system information, refer to Section 204-05 .
The air suspension module is used to monitor and control the VAPS system. The VAPS system controls the level of power assistance available to the driver based on vehicle speed and rate of change in steering position. For additional VAPS system information, refer to Section 211-00 .

My side mirros dont work


The exterior mirrors:
  • are controlled by power controls on the LH front door trim panel.
  • are of a foldaway design.
  • may contain turn signal indicators.
  • may be heated when the heated back window glass is activated.
  • may have a programmable recall memory option.
Driver Seat Module
The power driver seat and power exterior mirrors are controlled by the driver seat module (DSM) only when the vehicle is equipped with the programmable/recall memory option.
---------------------------------------------------------------------
Power Exterior Mirror Operation
The power exterior mirrors are controlled by the DSM and are operational all the time, whether the ignition switch is on or off. Using the power exterior mirror switch, the driver can adjust the driver and passenger exterior mirrors four ways.
