Lincoln Town Car Executive: Where is the canister vent valve

Video Link: https://www.youtube.com/watch?v=Xdwlvw8liIc JustAnswer https://www.justanswer.com > Lincoln Repair Aug 13, 2012 - Follow the EVAP hoses from the tank, you should see the vent valve mounted under the center of the trunk.

are you speakers blown? is it stock? do you get any static at all?

Some idea here https://www.cargurus.ca/Cars/Discussion-t16152_ds836069 Answered on Fixya before https://www.fixya.com/cars/t12836438-control_module_located_2003_lincoln https://www.google.com/search?q=2003+lincoln+town+car+body+control+module+location ..

Does the horn blow when you press the horn button on the steering wheel? If not I would first check the horn fuse ... then check the relay Swap it with a like relay (keeping in mind whatever you swapped it with won't work now if it is bad, or intermittant) ... owners manual will help with the locations of these.

The simplest things can cause the most trouble - I would start with a load test on the battery - may seem to be charged after using a battery charger, but can have plate connection problems causing failure under load.

Axel bearing most likely passenger side

Intermittent wipers are controlled by mufti-function switch (under steering wheel). However, Ford saw fit to include a 'rain sensor'. Located Windshield Front Center. Please provide more info if this doesn't help.

We would like to point out that your car already has a well-placed fuse box diagram located on the inside of the fuse box cover. However, if that's not the case visit this link to know where each fuse lays and what it does: https://knigaproavto.ru/shemy/en/lincoln/town-car/607-2003-2011-lincoln-town-car-fuse-box-diagram.html

no inline switch just a switch in the trunk driver side

When changing a battery alternate power supply should be hooked up so modules an radio don't lose settings . https://www.aa1car.com/library/battery_disconnect_problems.htm To get working again you would need to hook up a factory scan tool ,check codes , see if the control module for those systems can talk with the scan tool etc.... IF not , module would need to be replaced .

1. Verify the customer's concern.

1. Visually inspect for obvious signs of mechanical or electrical damage. Visual Inspection Chart Mechanical Electrical
   • Damaged exterior rear view mirrors
   • Damaged interior rear view mirror
   • Battery junction box (BJB) fuse(s):
     • 104 (40A)
     • 108 (30A)
   • Central junction box (CJB) fuse(s):
     • 17 (10A)
     • 18 (7.5A)
     • 28 (10A)
     • 30 (7.5A)
   • Damaged battery junction box (BJB)
   • Damaged central junction box (CJB)
   • Damage to wiring harness
   • Loose or corroded connections
   • Damaged exterior rear view mirror control switch

1. If the inspection reveals obvious concerns that can be readily identified, repair as necessary.

1. If the concern remains after the inspection, connect the diagnostic tool to the data link connector (DLC) located beneath the instrument panel and select the vehicle to be tested from the diagnostic tool menu. If the diagnostic tool does not communicate with the vehicle:
   • check that the diagnostic card is correctly installed.
   • check the connections to the vehicle.
   • check the ignition switch position.

If the diagnostic tool still does not power up, refer to the diagnostic tool manual.

1. Carry out the diagnostic tool data link test using the diagnostic tool. If the diagnostic tool responds with:
   • SCP+, SCP- or ISO circuit fault; all electronic control units no response/not equipped refer to Section 418-00 .
   • No response/not equipped for Driver Door Module (DDM), refer to Section 419-10 .
   • No response/not equipped for Driver Seat Module (DSM), refer to Section 419-10 .
   • If the DDM is not listed for a communication concern, turn the ignition switch to RUN, make sure all doors are closed, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs, then execute the Self-Test Diagnostics for the DDM. If the DDM exits diagnostic state during the self-test and returns to normal operation state, refer to Section 419-10 .
   • If the DSM is not listed for a communication concern, turn the ignition switch to RUN, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs, then execute the Self Test Diagnostics for the DSM. If the DSM exits the diagnostic state during the self-test and returns to a normal operating state, refer to Section 419-10 .

1. If the DDM DTCs retrieved are related to the concern, go to the Driver Door Module (DDM) Diagnostic Trouble Code (DTC) Index to continue the diagnostics.

1. If the DSM DTCs retrieved are related to the concern, go to the Driver Seat Module (DSM) Diagnostic Trouble Code (DTC) Index to continue the diagnostics.

1. If no DTCs related to the concern are retrieved, go to the Symptom Chart to continue the diagnostics.

There's a website that has all this information about all this and manuals everything totally free there are many actually but I personally like few .. let me know if u need help thanks

I have a owners Manuel with that page I do not know how to send it to you

P1235 - Fuel Pump Control Out Of Range Note: For LS6/LS8 and Thunderbird, the FPDM functions are incorporated in the Rear Electronics Module (REM). Also, the REM does not use a FPM circuit. Diagnostic information will be sent through SCP. P1235 indicates that the FPDM has detected an invalid or missing FP circuit signal from the PCM. The FPDM will send a message to the PCM through the FPM circuit, indicating that this failure has been detected. The PCM will set the DTC when the message is received.

• FP circuit open or shorted
• Electronic Throttle Control (ETC) system concern (check for ETC DTC P2105).
• Damaged FPDM.
• Damaged PCM

• The FPDM sends a 25% duty cycle (250 msec ON, 750 msec OFF) through the FPM circuit to the PCM while the fault is being detected by the FPDM. If the fault is no longer detected, the PDM will return to sending an "all OK" (50% duty cycle) message to the PCM. The PCM will keep P1235 stored in Continuous Memory.
• For LS6/LS8 and Thunderbird, check if Electronic Throttle Control (ETC) DTC P2105 is present. An ETC system concern could cause a P1235, and should be diagnosed first.

Note: Be aware that P1233/1234 could be set if the inertia fuel shutoff (IFS) switch was tripped then reset. Your best bet , take it to a qualified repair shop. C1123 Vehicle Speed Circuit Fault Overhead Console Module REFER to Section 413-08 .

When you turn the key to run or start is the theft light on or flashing ? Sorry but their is no deactivating , it's software programmed into the vehicle control systems . The dealer couldn't even do that with a factory scan tool . You need to see what DTC's - diagnostic trouble codes are stored , diagnose the problem and fix it .

has anyone checked for a vacum leak? a vacum leak will cause rough idle at idle. check the lines from the pcv valve.

the black will always be factory negative wire

What are the fault codes you are getting on a scanner.

where is the antenna wire located on the 2003 Lincon Town Car?
