Question about 2001 Lincoln Town Car

1 Answer

LCM power fuse #25 15amp fuse for C222 keeps blowing periodically

It seems to happen with the main light switch in "Auto" during the day, but I'm leaving it in "Off " now to check this theory. When it goes the interior lights don't work and head and tail lights are on all the time until the ignition switch is turned off.

The first place to start would be to have the LCM checked for DTC'S - diagnostic trouble code , rather then guessing .
B1689 Autolamp Delay Input Circuit Failure LCM GO to Pinpoint Test F . B1691 Autolamp Delay Input Circuit Short to B+ LCM GO to Pinpoint Test F . B1695 Autolamp ON/OFF Short to B+ LCM GO to Pinpoint Test F .
Inspection and Verification

  1. Verify the customer concern by operating the autolamps.
  1. Visually inspect for obvious signs of mechanical and electrical damage; refer to the following chart:


Visual Inspection Chart Mechanical Electrical
  • Headlamp switch
  • Autolamp switch
  • Autolamp sensor
  • Blown fuse(s)
  • Damaged wiring harness
  • Headlamp bulb
  • Loose or corroded connection
  • Lighting control module (LCM)

  1. If the inspection reveals obvious concern(s) that can be readily identified, repair as required.
  1. If the concern remains after the inspection, connect the New Generation STAR (NGS) Tester to the data link connector (DLC) located beneath the instrument panel and select the vehicle to be tested from the NGS menu. If the NGS does not communicate with the vehicle:
    • check that the program card is properly installed.
    • check the connections to the vehicle.
    • check the ignition switch position.
  1. If the NGS still does not communicate with the vehicle, refer to the New Generation STAR Tester manual.
  1. Perform the DATA LINK DIAGNOSTIC TEST. If the NGS responds with:
    • CKT914, CKT915 or CKT70 = ALL ECUS NO RESP/NOT EQUIP, refer to Section 418-00 .
    • NO RESP/NOT EQUIP for lighting control module (LCM), go to Pinpoint Test A.
    • SYSTEM PASSED, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs and perform self-test diagnostics for the LCM.
  1. If the DTCs retrieved are related to the concern, go to the LCM Diagnostic Trouble Code (DTC) Index to continue diagnostics.
  1. If no DTCs related to the concern are retrieved, proceed to Symptom Chart to continue diagnostics.
  2. LCM Diagnostic Trouble Code (DTC) Index DTC Description DTC Caused By Action B1312 Lamp Headlamp Input-Short to B+ LCM GO to Pinpoint Test D . B1334 Decklid Ajar-Short to Gnd LCM REFER to Section 501-14B . B1340 ESC Tone Request Short to Ground LCM REFER to Section 501-14B . B1342 ECU-Defective LCM REPLACE the LCM. REFER to Section 419-10 .

One of the tail light bulbs can be shorted internally.  Replace the tail light bulbs first.  Try this cheap fix first.

SOURCE: Park/Tail lights not working. Brake/signals are

Before going ahead and spending money on a new module, test it first. The module is located under the steering column. You'll find a Brown wire on one of the connectors (i just looked at a wire diagram). Do no disconnect anything. Back probe the brown wire, which is the power feed to your park lights. With the lights off, there should be 0 volts on you voltmeter. Turn the park lamps on, There should be 12V. If there is not 12V, disconnect the connector and try to check voltage at the pin that feeds to the brown wire, if still not 12V, replace the module. If you do get 12V, then module is ok, find where the 12v is being dropped before making it to the lamps.

Is the fluid full enough? there should be a dipstick to tell where the level should be. Also is the belt tight enough? Wires loose?

Under system click on lighting ,then under subsystem click on turn signal lamp . Click the search button then the blue links.
How to find automotive electrical shorts

Principles of Operation
The lighting control module (LCM) controls the flashing of the turn signal and hazard lamps. Power is routed through the multifunction switch to the LCM. When the multifunction switch is placed in the LH turn, RH turn or hazard lamps ON position, the LCM will command those lamps on and off.

have it checked for DTC'S diagnostic trouble codes

2005 merc grand marquis Headlights keep blowing a fuse


Does your Grand Marquis have head lamps with auto lamps ? Which fuse keeps blowing ? Could be a shorted LCM - lighting control module ?

Lighting Control Module (LCM)
The LCM eliminates the electronic interference and heat associated with the thermoelectric devices used previously. The LCM is a microprocessor-based module that controls several vehicle subsystems. It responds to electrical input signals from various switches, sensors, and external modules..

My cigerate liter stoped working and radio and horn Fuze keeps blowing I banged on my dash board and all.this happened


Hi Erik, I'm Al the owner of Big A's Auto Repair
Erik, this is call the process of elimination, what you'll need to do is unplug the liter wiring and see if it still blows the fuse. Most of the time when the liter element goes bad it because it has an eternal short. If it still blows the fuse, hook it back up and unplug the radio, if it still blows the fuse, then you may have wiring shorting out somewhere behind the dash. NOTE: If the short does go away during the process of elimination. Then you'll need to replace the thing that was causing the short. If you need further assistance go to my website. Have an awesome day Erik.

Replace dimmer switch


The headlamps ( high an low ) are controlled by the LCM lamp control module .
Headlamp Dimmer Switch
Under the left side of the IP, on the base of the steering column

Headlights Circuit Description (Buick)
Battery positive voltage (B+) is supplied at all times to the lamp control module (LCM) through the LH underhood fuse block LCM/HDLP circuit breaker via CKT 242 (RED). When the headlamp switch is placed in the ON position, the headlamp switch input to the LCM is grounded via CKT 103 (WHT). The LCM then supplies battery positive voltage (B+) via CKT 12 (TAN) to the following components:
• Left low beam headlamp
• Right low beam headlamp
When the headlamp dimmer switch is placed in the HIGH position, the LCM removes battery positive voltage (B+) from the low beam headlamps. The LCM supplies battery positive voltage (B+) via CKT 11 (LT GRN) to the following components:
• Left high beam headlamp
• Right high beam headlamp
The LCM provides battery positive voltage (B+) to the appropriate headlamps under the following conditions:
• The ignition switch is in the RUN position.
• The ambient light sensor indicates darkness.
The lamp control module (LCM) monitors the ambient light conditions through the ambient light sensor. The ambient light sensor is a variable resistor whose resistance changes as the surrounding ambient light level changes. As the ambient light decreases, the resistance of the ambient light sensor increases. The LCM measures the resistance across the ambient light sensor and determines whether it is day or night.

My 2002 ford ranger running lights and instrument panel dont work


12V power passes through 15A fuse 33 (the one that keeps blowing?) in the battery junction box and on to the main light switch. When the main light switch is set to PARK, 12 volts is routed via the BRN lead to the park filaments of the dual park/turn lamps. These lights remain on when the headlight switch is turned to HEAD.

The main light switch gets its 12V input from 7.5A fuse 11 in the central junction box and the same 15A fuse (33) identified above. When the main light switch is set to PARK, 12 volts is routed via the BRN lead to the instrument panel dimming module and module output is applied to the panel illuminating lamps.These lights remain on when the headlight switch is turned to HEAD.

The input to fuse 33 is hot all the time so should read 12V. If you read 12V at the TAN/WHT connection with the fuse out, something is definitely not right. I'm sure you have noted that the fuse is common to the non-functioning circuits you mentioned.

My 2005 buick rendezvous keeps blowing the fuse for the turn signals and brake lights. Fuse #42 in the inside fuse panel. this just started happening two days ago. Nothing is different with the car.


most likely caused by a short, could be any were. start with the light assembleys remove it and clean any rusty or coroded spotspull all bulbs clean and or replace .auto parts stores sell an electrical parts wash about 9 to 14 $ . spray as needed let dry and put back together.if it still blows fuses its some ware in the wire s , could also be at the turn signal switch or the brake switch . you would have to get it to blow to figure out witch one it is and witch one it is not example put in new fuse then keep putting on the brakes if not blown then keep doin the turn signal then check to see if blown

Insrument panel loses power periodically


this is just a loose fuse or connector wiggle the connector of the lighting control module just above you gas pedal under the dash.turn lights on try to kick slightly the module(black metal box).Sometimes you need to open it and re apply heat and solder on the relay terminals fixed on the board.
