I have a 06 Lincoln Zephyr and the left front turn signal stays on constantly at it runs my battery down and my right front turn signal when you turn it on comes on for 1 blinks 1 time and don't blink no...


Without test we would only be gussing . Could be the SJB - smart junction box , electronic module problem ,wiring problem ,switch etc... Looking at wiring diagrams an testing the circuit's with a DMM - digital multi-meter , would be the way a professional technician would diagnose this . Hooking up a factory or professional type scan tool an checking for DTC'S - diagnostic trouble code's also .
The smart junction box (SJB) monitors the multifunction switch position by sending multiple voltage reference signals to the multifunction switch. When the multifunction switch is in the LH or RH TURN positions, or the hazard lamp switch is engaged, that input signal is routed to ground.
When the SJB receives a request for a turn signal or hazard lamps, the SJB supplies voltage to the appropriate turn lamps.

2007 Lincoln Navigator Turn signal relay location?


It doesn't have one Controlled by smart junction box .
The smart junction box (SJB) monitors the multifunction switch position by sending multiple voltage reference signals to the multifunction switch. When the multifunction switch is in the LH or RH TURN positions, or the hazard lamp switch is pressed, that input signal is routed to ground.
When the SJB receives a request for a turn signal or hazard lamps, the SJB supplies voltage to the appropriate turn lamps.
The timed on/off cycle is determined by the SJB and is set to flash approximately 80 times per minute if both the front and rear turn lamps operate correctly. If an individual turn signal lamp is inoperative, the SJB flashes the remaining turn lamp approximately 160 times per minute.

Where's headlight relay @ on a 2010 ford fusion 2.5


There is no relay for low beams , the ( SJB) smart junction box , a control module an fuse / relay center in one.
When the SJB receives an input requesting the headlamps on, the SJB supplies voltage to the low beam and high beam bulbs as necessary.
The smart junction box (SJB) monitors the headlamp switch position by sending voltage reference signals on multiple circuits to the headlamp switch. At any given time, one of the signal circuits is routed to ground. If the SJB does not detect any of the inputs to the headlamp switch is active (routed to ground) for 5 seconds, the SJB turns on the exterior lights and keeps them on for 10 minutes after the ignition switch is turned off (or 10 minutes from the time the SJB does not detect any headlamp switch input if the ignition switch was already off). If the SJB detects multiple circuits short to ground, the SJB implements a planned strategy depending on the multiple inputs received. If either of these situations occur, the SJB should NOT be ruled immediately as being at fault. This is normal behavior of the SJB design as it has detected a fault with the inputs from the headlamp switch.

2008 ford explorer light control module


Hi Rich , what lights are you talking about ? Exterior Lighting , Interior Lighting ? It doesn't matter All lights are controlled by SJB smart junction box ! An you can't just stick in a used one , It will need to be programmed ! Interior Lighting The interior lighting system consists of the following components:
  • Smart junction box (SJB)
  • Dimmer control switch
  • Interior/map lamps
  • Cargo lamp
  • Glove compartment lamp
  • Vanity mirror lamps
  • Door ajar switches
  • Puddle lamps
The interior lighting system consists of 2 subsystems:
  • Courtesy lamps
  • Demand lamps
The courtesy lamps are controlled by the SJB. The courtesy lamp subsystem consists of the interior dome lamps, the puddle lamps and the overhead console lamps (if equipped). The SJB supplies voltage to the courtesy lamps when the SJB receives the required input.
The demand lamps are controlled by the SJB. The demand lamps subsystem consists of the glove compartment lamp, all map/reading lamps, and the left and right vanity mirror lamps.
The SJB supplies power to the interior lighting system. The SJB will set DTCs if certain circuit failures exist with the interior lighting system.
Exterior Lighting Headlamps
The headlamp system is a dual-beam pattern system. It consists of a low and high beam, with a replaceable bulb. The headlamp assembly has the park/turn indicator lamp integrated into the headlamp assembly. The smart junction box (SJB) supplies voltage to the headlamps when demanded.
Principles of Operation
The SJB receives inputs and delivers outputs to a majority of the electronically-controlled features of the vehicle. The SJB constantly monitors the systems under its control and reports a concern in the form of a DTC. The DTC can be retrieved with a scan tool through the medium speed controller area network (CAN) communication network.
NOTE: Prior to the removal of the SJB, it is necessary to upload the module configuration information to the diagnostic tool. This information must be downloaded to the new SJB after installation. For additional information, refer to Section 418-01 .

2009 ford escape turn signals and brake lights work but no taillights checked bulbs look good no where in owners mannual does it list tailight fuse or location


I think your problem locating the fuse may be because Ford refers to the lights you are describing as "PARK" lamps, instead of "TAIL" lamps. The PARK fuse is Fuse #22 (15 Amp) located in the Smart Junction Box (SJB) in the center of the dash.

HINT: This same fuse also protects the circuits your front park lamps, if they are working, the fuse is not blown.

Need turn signal flasher module


Has no flasher module , uses SJB - smart junction box . FORD'S BCM - body control module .
The smart junction box (SJB) monitors the multifunction switch position by sending multiple voltage reference signals to the multifunction switch. When the multifunction switch is in the LH or RH TURN positions, or the hazard lamp switch is engaged, that input signal is routed to ground.
When the SJB receives a request for a turn signal or hazard lamps, the SJB supplies voltage to the appropriate turn lamps.

You could by a used one off ebay or a remanufactured one . lot less cost wise. But you would need ford , mercury dealer program it . Yes $600 bucks sounds right from the dealer .

Can't find the flasher relay on a 2008 superduty


It doesn't actually have one this function is incorporated into the smart junction box.
The SJB monitors the multifunction switch position by sending multiple voltage reference signals to the multifunction switch. When the multifunction switch is in the LH or RH TURN positions, or the hazard lamp switch is pressed, that input signal is routed to ground.
When the SJB receives a request for a turn signal or the hazard lamps, the SJB supplies on/off voltage to the appropriate turn lamps.
The timed on/off cycle is determined by the SJB and is set to flash approximately 80 times per minute if both the front and rear turn lamps operate correctly. If an individual turn signal lamp is inoperative, the SJB fast flashes the remaining turn lamp approximately 160 times per minute to indicate to the driver of a bulb outage.
The SJB bulb outage is configurable and can be turned off for the rear lamps. This is to accommodate vehicles that have been upfitted with rear LED lamps in place of the traditional incandescent bulbs.

Tail lights wont come one


Do you know what a smart junction box is ? This fords BCM - body control module .( computer )
The smart junction box (SJB) monitors the headlamp switch position by sending multiple voltage reference signals to the headlamp switch. When the headlamp switch is in any given position, that input signal is routed to ground.
When the SJB receives an input from the headlamp switch indicating a request for the parking lamps, the SJB energizes the parking lamp relay, which supplies voltage to the exterior lamps.

Pinpoint Test Q: One Or More Parking, Rear or License Plate Lamps Is Inoperative
Normal Operation Voltage is supplied to the smart junction box (SJB) from the battery junction box (BJB) fuse 23 (60A) through circuit SBB23 (WH/RD).
When the headlamp switch is placed in the PARKING LAMPS ON position, the SJB provides a ground for the parking lamp relay coil (internal to the SJB). When the parking lamp relay is energized, voltage is sent through circuit CBP08 (GY/YE) to the rear and front parking lamps. Ground is provided to the rear parking and license plate lamps through circuit GD171 (BK/GY). Ground is provided to the front parking and side marker lamps through circuits GD121 (BK/GY), GD121 (BK/RD), GD121 (BK/YE), GD121 (GY/YE), GD123 (BK/YE) or GD123 (BK/GY).
    Possible Causes
  • Fuse
  • Circuit CBP08 (GY/YE) open
  • Circuit GD121 (BK/GY) open
  • Circuit GD121 (BK/RD) open
  • Circuit GD121 (BK/YE) open
  • Circuit GD121 (GY/YE) open
