It may not be easy, but it sounds like a ground wire is corroided or loose. You will need a good shop manual to locate the grounds for that component. Sometimes the dealship will run you off a copy of the wiring diagram since your auto parts store more than likely won't carry that.

Heated driver seat doesn't heat on 2001 Buick Regal GS


You have probably burnt up the element as it is a 17 year old seat now. The elements are replaceable, but the labor is pretty spendy. To test it you will need a multimeter to check for continuity across the connectors that go to the seat heating elements and check for voltage at the car side of the connector. If you have 12v to one side of the connector and continuity to ground at the other side, and do not have continuity to the seat side between the connectors, you know it is a bad element.

What is the fuse number for the dashboard lights on a 2007 Ford Focus 3 door hatchback?


Principles of Operation
The instrument cluster and panel illumination consists of dimmable and non-dimmable illumination components. The dimmable illumination is controlled by the instrument panel dimmer switch, which allows the brightness level of the backlights to be adjusted to the customer preferences. With the parking lamps ON, the instrument panel dimmer switch uses electronic circuitry to provide a variable pulse width modulated (PWM) output to the instrument panel and all applicable switches depending on the driver-controlled level of intensity. The headlamp switch backlighting consists of 2 constantly illuminated LED bulbs that are powered by separate circuits. Battery voltage is supplied to the first bulb when the ignition switch is in the RUN position. Battery voltage is supplied to the second bulb with the parking lamps ON. The non-dimmable illumination allows for full intensity dependant on the ignition switch position.

Inspection and Verification
  1. Verify the customer concern.
  1. Visually inspect for obvious signs of mechanical or electrical damage.


Visual Inspection Chart Mechanical Electrical
  • Headlamp switch
  • Instrument panel dimmer switch
  • Circuitry
  • Connector(s)

How do i bim and brighten dash light 2002 buick lesabre


bim or DIM ? the dimmer switch ! Interior Lamps
The interior lamps consists of two groups, lamps that can not be dimmed and lamps that can be dimmed. This first group consists of lamps that may not be dimmed. This includes those lamps that may be manually turned on by placing the interior lamp switch to the DOME position, or by opening a door or a compartment:
• Door courtesy lamps
• Footwell courtesy lamps
• Instrument panel (I/P) compartment lamp
• Overhead console courtesy lamps
• Reading courtesy lamps
• Rear compartment courtesy lamp
• Roof rail courtesy lamps
• Sunshade vanity mirror lamps

Interior Lamps Dimming
This group of interior lighting includes lamps which may be dimmed. This group uses a combination of class 2 controlled illumination and incandescent lamps:
• Air temperature switch
• Cigar lighter lamp
• Door switches
• Driver information center (DIC) switch
• Headlamp switch
• Head-up display (HUD) switch
• Heated seat switches
• HVAC control assembly
• Instrument panel cluster (IPC)
• Memory function switch
• Radio
• Steering wheel controls
• Window switches
For the interior lighting to be dimmed the following conditions must be met:
• A low light level has been detected by the dash integration module (DIM)
• Headlamp switch is placed in to the PARK or HEAD position
• Ignition switch is placed in the ON position
Then all class 2 displays and all incandescent back lighting will be illuminated to the level set by the instrument panel (I/P) dimmer switch. When the I/P dimmer switch is moved from MIN to MAX, all class 2 displays and all incandescent back lighting respond from minimum intensity to maximum brightness.
The DIM supplies battery positive voltage to the coil side of the PRK LP relay in the rear fuse block.
When the I/P dimmer switch is moved from MIN to MAX, then the instrument panel module (IPM), W/CJ2, or climate control panel (CCP), W/C67, applies a message to the class 2 communication circuit to the DIM. The DIM then applies a ground to the park lamp relay control circuit. This energizes the PRK LAMP relay and allows battery positive voltage to be applied through the DIMR fuse to the DIM. The DIM then illuminates the following incandescent lamps through the incandescent dimming output circuit:
• Cigar lighter lamp
• DIC Switch
• Headlamp switch
• HUD switch
• HVAC control assembly
• IPC
• Radio
• Steering wheel controls
The DIM also applies a message to the following class 2 controlled illumination components:
• Drivers door module (DDM)
• HVAC control assembly
• IPC
• Radio
The DDM will then send a message through the simple bus interface (SBI) to the RH front door module (RFDM). The door modules will then illuminate the following components through the incandescent dimming output circuit:
• Air temperature switch
• Heated seat switches (W/KA1)
• Memory function switch (W/A45)
• Power door lock switches
• Power window switches
The ground for these components are provided from the DDM and RFDM.
The following components are grounded at G200:
• Headlamp switch
• HVAC control assembly
• IPC
• Radio
• Steering wheel controls
The following components are grounded at G201:
• Cigar lighter lamp
• DIC Switch
• HUD switch

Trying to find which fuse is for the heated seats on a 2004 ford explorer sports trak


Heated Seats
This system allows the electrical heating of the front seats on passenger demand.
The components of the system are:
  • the seat heating elements located in the seat cushion and backrest.
  • the heated seat control switch, located on the seat side trim panel.
  • temperature sensors located in the seat cushion heating elements.
  • heated seat relay.

Having the vehicle checked for DTC'S - diagnostic trouble code's would probably be your best course of action .
DTC B2556 (1)
The I/P dimmer switch is a potentiometer. The instrument panel module (IPM) determines the control setting based on the voltage from the I/P dimmer switch. The IPM sends out a class 2 message to the dash integration module (DIM). The intensity of the interior backlighting shall be adjustable when ever the park lamps are on. The intensity of the vacuum florescent displays shall only be adjustable when it is night and the park lamps are active.
DTC B2627
DTC B2628
Circuit Description
The I/P dimmer switch is a potentiometer. It is powered by the HVAC control module. The HVAC control module determines the level of dimming desired based on the voltage from the I/P dimmer switch. The HVAC control module converts the I/P dimmer switch feed back voltage to a digital signal and puts it on the Class II communication bus.

Dash Integration Module (DIM)
The DIM is wired to the class 2 serial data line. The various DIM input and output circuits are described in the corresponding functional areas as indicated on the DIM electrical schematics.
The DIM functions include the following:
• Control of headlights and exterior lamps
• Horn relay control
• Interior lamps incandescent dimming
• Lamps On signal with wiper/washer
• Power moding control over Class 2 serial data line
• Steering wheel controls
• Storage of the clock settings and, sending a message out on the class 2 serial data circuit in response to requests from other modules

Your best bet ,take your vehicle to a qualified repair shop.
