Try your local junkyard. I have had the best luck finding parts at a Automotive recycling plant called LKQ

On my 2002 Saturn L100, the passenger headlight is only showing 5 volts instead of the normal 12 volts, whats wrong ?


bad ground wire for the light
check both sides of the bulb as one will be 12 volts and the other considerable less because of the high resistance of the filament of the bulb

2000 cadilac seville occasionally doesnt respond when ignition key is inserted, no memory position adjustments, no starter when key turned. is it key or ignition switch. everything usually works fine


Is the security light lit on the instrument when it doesn't start ? The ignition switch on your vehicle doesn't work like you would probably think it does . The ignition switch is input signal to the body control system .
Body Control System Description
The body control system consists of three modules and their associated electrical controls. These modules are as follows:
• The dash integration module (DIM), located on the right hand side of the instrument panel, near the blower motor.
• The instrument panel integration module (IPM), located in the center of the instrument panel, above the radio.
• The rear integration module (RIM), located on the right hand rear of the passenger compartment, behind the rear seat.
Each module integrates input and output controls for two or more functional areas. The inputs and outputs are wired to the closest module to minimize the lenth and amount of the wiring used. All three modules communicate on the Class 2 serial data line, allowing data to be shared among them, as well as with other Class 2 modules on the vehicle as needed.

Each of the three body control modules integrate a number of functional systems under the control of a single module. Each of the modules are connected to the Class 2 serial data line.
Dash Integration Module (DIM)
The dash intergration module (DIM) functions include the following:
• Power moding control (ignition switch states) over Class 2 serial data line
• Control of exterior lamps
• Interior lamps and incandescent dimming
• Steering wheel controls
• Horn relay control for theft activation
• Low side temperature for HVAC compressor
• Hood ajar switch input (export)
• Storage of the clock settings and, sending a message on the class 2 serial data line in response to requests from other modules.

Instrument Panel Integration Module (IPM)
The instrument panel integration module (IPM) functions include the following:
• Front HVAC air delivery and temperature controls
• Ambient light sensor input and twilight delay input for headlights control
• Foglight switch inputs
• I/P dimmer switch input
• Traction control switch input
• Interior lamps switch input
• Key in ignition switch input from the ignition switch
• Fuel door and rear compartment lid release switch input
• Ignition switch headlight control

Rear Integration Module (RIM)
The rear integration module (RIM) functions include the following:
• Fuel level sensor input
• Heated seat controls
• HVAC blower control
• Rear defogger control
• Park brake relay controls
• Various controls for the interior lamps
• Reverse control for the backup lamps and automatic day/night mirror
• Rear foglights control
• Fuel door and rear compartment lid release controls
• Retained accessory power (RAP) control for the sunroof control module
• Ajar switch and tamper switch inputs from the rear compartment lid
• Content theft alarm

At the dealer we would hook up a scan tool and look at the ignition switch inputs to the DIM to see if has correct inputs . Also we would check DTC'S diagnostic trouble codes .
DTC B1805 Ignition Switch Problem

Normal vehicle Class 2 communication does not begin until the system power mode has been identified. The dash integration module (DIM) monitors four discrete wires from the ignition switch contacts in order to determine the present power mode (ignition switch position). The DIM communicates the system power mode to all Class 2 modules on the Class 2 serial data line.

Climate control panel lighting is dim and sometimes does not turn on unless i knock on the instrument panel


There are tiny 12 volt DC bulbs that are soldered to the circuit board inside the climate control head, you must remove the module, take it apart and replace those bulbs. You can buy the bulbs at Radio Shack Part #7219

2000 LeSabre BCM Suspect


The first thing the dealer would do is diagnostic's . Would not guess and just replace the BCM . Hooking up the factory Tech 2 scan tool an checking for DTC'S - diagnostic trouble codes , input data to the BCM etc.
(I have reason to believe the BCM in my 2000 LeSabre is bad ???? )you have no clue ! The BCM has nothing to do with gauges , insturment cluster ! Beside's you still would need to take it to the dealer because it would need to be programmed .
Leave this to a qualified repair shop . Plus the dash doesn't need to be taken apart to replace the BCM . Your vehicle actually has three modules for the body control system .
The body control system consists of 3 modules:
• The dash integration module (DIM)
• The instrument panel module (IPM)
• The rear integration module (RIM)
You have no idea what your messing with . Your best bet ,take it to a qualified repair shop ,and that doesn't always mean you need to take it to the dealer .
Each of the 3 body control modules integrate a number of functional systems under the control of a single module. Each of the modules is connected to the Class 2 serial data line. Many control signals are implemented by Class 2 messages.
Important: The air bag indicator light may remain ON after the DIM module is replaced, and during the programming procedure for the DIM, until after the procedure is completed and the ignition key is cycled OFF and ON .
• Before replacement, record the personalization settings to transfer to the new module (if they are available).
• After replacement of the DIM, perform the following procedure.
• In order to reprogram the DIM, perform the following procedure.
Using a scan tool, preform the New VIN Procedure.
Perform the Setup SDM Serial Number in DIM Procedure.
Using the scan tool, set the Point of Sale in the DIM module to the correct country.
Using the scan tool, configure the RPO option configuration.
Perform the vehicle personalization in order to reset the owner's desired personalization settings. Refer to Instrument Cluster, Gauges and Console.
Plus power door locks and windows are controlled by door module system , not body control system .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.
Mess with the wrong stuff an you will render your vehicle useless
cost to much to fix.

Instrument panel lights do not come on.


Soldering the new bulbs in may have done something to the LH DIMMER MODULE ! The 10amp INT LPS fuse located in the I/P fuse box is good ? Is the dimmer switch at full bright ?
When the park lamps are on, battery positive voltage (B+) is supplied through the instrument panel (IP) fuse block INT LPS fuse via CKT 32 (YEL) to the dimming switch. The dimming switch supplies a variably controlled voltage to the dimmer module(s). The potentiometer in the panel dimming control cannot provide enough current in order to operate the panel lamps. The dimmer module(s) amplifies the current, supplying the variable voltage to the panel lights. As the amount of the current increases, the lamps become brighter. As the amount of the current decreases, the lamps become dimmer.
Buick
There is only 1 dimmer module that supplies current to the panel lights. The left dimmer module supplies current via CKT 8 (GRY) to the following components:
• The headlamp switch
• The door switch flood lamps
• The heater and A/C control
• The door handle flood lamps
• The passenger temperature control
• The ashtray lamp
• The shift select switch lamp
• The instrument cluster
• The steering wheel controls
• The reset switch
• The trip odometer
• The radio
Parade Dimming
The parade dimming feature prevents the dimming of the VF displays when daylight is sensed by the lamp control module (LCM) and the park lamps are turned on manually. If the LCM senses night time conditions and the park lamps are on, the LCM allows the VF displays to be dimmed.
All of the modules with the VF displays receive the dimming level from an input on CKT 8 (GRY) or CKT 1244 (BRN). When the LCM determines that the above conditions are met, the LCM sends a signal to the instrument cluster and the radio via CKT 390 (YEL). For Buick, the radio then relays this information to the heater and A/C programmer and passenger temperature control via CKT 724 (PPL/WHT). The modules with the VF displays then adjust the dimming level of their VF displays to match the level of the incandescent lights.

Xenon headlight problems


there are 3 things that make the xenon in your car work the bulb, an ignitor, and a control module, you know your bulbs are ok so thats good, now you will want to swap the control modules they are a metal box attached to the headlight assembly its roughly 4"x4" you will remove the hheadlight assemblys to get to the module, there are 4 8mm bolts and then it pulls out, it the light follows the control module then thats what you will need if not you will need an ignigtor, as far as the flickering that is moet likely the module going bad, the company that makes this system is AL (automotive lighting) there is an SIB from BMW about this that says under a warr claim both control modules are to be replaced and the bulb of the faulty headlight, however i cant count the number of times i have done all that and still have to replace the ignigtor, If it is the Ign that is alot harder to swap as you have to dis assembly the entire light assembly

2004 Dodge Ram Pick up. The instrument lights for the fan controls -heating cooling are real dim. What does it to take to change these lamps out? Pulled the control knobs off but not sure what to do next.


The controls for fan speed, temp and air flow are contained in a self-contained control module attached to the center dash. To get to the lights, you have to remove the center dash unit (refer to the 1st diagram for removal).b5f7dfa.jpg Once the center dash is removed, turn it over and you will see three bulbs (you will actually see the base of the bulbs--refer to the 2nd attachment for illustration). d6d29c8.jpg
Simply remove the bulbs with a narrow blade, flat screwdriver. The Mopar Part Number for the bulbs is: 50138115AA. I paid about $2.25 for each bulb. Let me know if you need more info.

1990 honda accord ex..dim running lights


Dim lamps are ususally caused by a bad ground, however, first things first, have you replaced any tail light or signal bulbs lately? if so, there's your culprit - the wrong bulb or incorrectly installed, - otherwise, it is either a bad ground (Wiring diagram) or a bad lighting control module.
