    Spirit, Acclaim, LeBaron Sedan, Shadow and Sundance

    See Figure 2

    The fuse block is located behind the steering column cover, accessible by removing the fuse access panel above the hood latch release lever. The relay and flasher module is either located behind the fuse panel or behind an access panel in the glove box. Included in the module are the hazard and turn signal flashers along with the time delay and horn relays. Additional relays are mounted on the inner fender panel near the battery.

    Daytona and LeBaron Coupe/Convertible

    The fuse block is located behind a removable access panel to the left of the lower portion of the steering column. On 1988-89 Daytona and LeBaron, the hazard and turn signal flashers along with the time delay and horn relays are also located behind the panel.

    On 1990-92 Daytona and LeBaron, a relay bank is located on the left side kick panel. The Power Distribution Center, which contains additional relays and fuses, is located in the engine compartment behind the battery. Each item is identified on the cover.

    Dynasty, New Yorker, Fifth Ave. and Imperial

    See Figure 3

    On vehicles without a Power Distribution Center, fusible links are part of the the large wiring harness behind the battery. On vehicles with a Power Distribution Center, fusible links in the form of cartridge fuses, which resemble small relays but serve as fusible links, are located in the Center. Each item is identified on the cover of the Power Distribution Center.

    The fuse panel, which contains fuses and circuit breakers, is located behind the glove box door. To remove the panel, pull it out from the bottom and slide the tabs out from the top. Additional fuses are in the Power Distribution Center located near the left side strut tower in the engine compartment. Each item is identified on the cover of the Power Distribution Center.

    Fig. Fig. 3: Relay and flasher module-Dynasty, New Yorker (1989-93), Fifth Ave. and Imperial

    There is an additional relay module (relay and flasher module) located to the right lower corner of the instrument panel (Dynasty, Imperial and Fifth Ave.) or behind the cup holder (New Yorker). A relay or flasher can be removed by pulling it straight down from the module.

    Premier and Monaco

    The fuse panel is located above the parking brake release lever, under the instrument panel. On Monaco built on or after October 9, 1991, various cartridge fuses are in the Power Distribution Center, located on the left side of the engine compartment,

    Fusible links are used to prevent major wire harness damage in the event of a short circuit or an overload condition in the wiring circuits which are normally not fused, due to carrying high amperage loads or because of their locations within the wiring harness. Each fusible link is of a fixed value for a specific electrical load and, should a link fail, the cause of the failure must be determined and repaired prior to installing a new fusible link of the same value.

    Circuit breakers are an integral part of the headlight switch, the wiper switch and the air conditioning circuit. They are used to protect each circuit from an overload. Other circuit breakers are on the fuse panel.

    Relays are used throughout the system in various locations. When replacing a protective electrical relay, be very sure to install the same type of relay. Verify that the schematic imprinted on the original and replacement relays are identical. Relay part numbers may change. Do not rely on them for identification. Instead, use the schematic imprinted on the relay for positive identification.

    On vehicles built before October 9, 1991, a relay bank is located on the left side of the engine compartment. On vehicles built on or after October 9, 1991, the Power Distribution Center is used in the same location and is equipped with additional fuses. Additional relay locations are as follows:



    Power door lock relay -is located on the right side kick panel.
     
    Passive restraint relays -are located under the seats.
     
    Light outage module -is located behind the right side speaker in the trunk.
     
    Passive restraint control module -is located on the left side of the trunk.
     
    Headlight module -is located under the left side of the instrument panel.
     
    Daytime running light module -is located in the right front area of the engine compartment.
     
    Climate control relays and module -are located under the right side of the instrument panel.
     
    Sun roof relay -is near the sun roof motor.
     

    The turn signal flasher is located behind the left side of the instrument panel. The hazard flasher is located behind the left side of the instrument panel.

    REPLACEMENT



    Fuses

    See Figures 4, 5, 6 and 7


    WARNING
    When replacing a blown fuse, it is important to use only a fuse having the correct amperage rating. The use of a fuse with a rating other than indicated may result in a dangerous electrical system overload. If a properly rated fuse continues to blow, it indicates a problem in the circuit that must be corrected.

    The models covered by this information guide use blade type fuses. The fuses have the amperage printed on the outer edge and are also color coded according to amperage rating.

    Make sure to note the amperage rating before discarding a blown fuse! Always replace the fuse with one of exactly the same rating, as use of a rating even slightly higher than standard could result in a dangerous vehicle fire.

    If a circuit continues to blow a fuse of the proper rating, leave the fuse out and check the circuit or the accessories it runs for an electrical short or mechanical overload.

    Remember, in replacing the access panel, to insert the tabs at the top first and then to snap the locking tabs at the bottom into place.

    Fusible Links

    See Figure 8

    The main wiring harnesses are equipped with fusible links to protect against harness damage should a short circuit develop.

    Never replace a fusible link with standard wire. Only fusible link wire of the correct gauge with hypalon insulation should be used.

    Fig. Fig. 8: On newer vehicles, the fusible links are easily identified by their markings

    When a fusible link blows, it is very important to locate and repair the short. Do not just replace the link to correct the problem.

    Always disconnect battery negative cable when servicing the electrical system.

    1. Disconnect the negative battery cable.
    2.  
    3. Cut off the remaining portion of the blown fusible link flush with the multiple connection insulator. Take care not to cut any of the other fusible links.
    4.  
    5. Carefully remove about one inch of insulation from the main harness wire at a point one inch away from the connection insulator.
    6.  
    7. Remove one inch of insulation from the replacement fusible link wire and wrap the exposed area around the main harness wire at the point where the insulation was removed.
    8.  
    9. Heat the splice with a high temperature soldering gun and apply resin type solder until it runs freely. Remove the soldering gun and confirm that a "bright'' solder joint has been made. Resolder if "cold'' (dull) joint has occurred.
    10.  
    11. Cut the other end of the fusible link off at a point just behind the small single wire insulator. Strip one inch of insulation from fusible link and connection wires. Wrap and solder.
    12.  
    13. After the connections have cooled, wrap the splices with at least three layers of electrical tape.
    14.  

    Flashers

    Flashers are located either on the bottom of the fuse block or on a module under the dash. They are replaced by simply pulling them straight out. Note that the prongs are arranged in such a way that the flasher must be properly oriented before attempting to install it. Turn the flasher until the orientation of the prongs is correct and simply push it firmly in until the prongs are fully engaged.
